  • The 6 Grammar Rules That Separate a 700 from a 780 on the SAT

     

     

    Grammar is the section of the SAT where you can score 100%. It’s about mastering Levels 5 and 6 so completely that you sail through them without dropping a single point. The students who break 1500 are the ones who never get an easy or medium grammar question wrong.

    You need to memorize the rules and practice them until they are automatic. There are six broad grammar topics that matter most.

    Bluebook practice tests won’t give you enough practice to ensure zero mistakes. Most grammar questions are medium difficulty. But they seem hard because grammar is not formally taught in schools. And you’ll only see a handful of hard ones per test. Bluebooks do not offer enough repetition to build speed or consistency.

    College CoPilot’s Hard Grammar Test is built entirely from the grammar questions that appear on the SAT. Timed, so you can build accuracy under speed. When you get one wrong, Dakota, our AI tutor, walks you through the rule and why that answer choice was designed to fool you.

    Check your score report. If you’re losing points on Standard English Conventions, this is the fastest fix. 

    The 6 Rules: A Study Guide

    Below are the six rules with a real SAT example and key hint for each. We’ve grouped them into two categories:

    –Boundary questions: where does one idea end and another begin?
    –Form, Structure & Sense questions: errors you can’t hear.

    Boundary Questions

    1. Nonessential Clauses and Parenthetical Asides

    A nonessential clause is an aside. You can remove it without changing the core meaning of the sentence. It must be punctuated on both sides with matching marks: two commas, two dashes, or two parentheses. Mixing punctuation is always wrong on the SAT.

    Key hint:
    Find the aside, then check that both ends are punctuated the same way.The SAT often separates the opening and closing punctuation so far apart that students spot one and miss the other.
    Example
    With some 16,000 in attendance, the Second World Black and African Festival of Arts and ______ or FESTAC ’77,
    as the event was more commonly known—became the largest pan-African event on record.
    A) Culture:  B) Culture—  C) Culture,  D) Culture
    Answer: B.
    The dash after “known” closes a nonessential aside. The opening punctuation must match — so you need a dash after “Culture” as well.
    A comma cannot pair with a dash, even if it “looks fine.”

    2. Coordinating Clauses and FANBOYS

    When two independent clauses are joined by a coordinating conjunction (for, and, nor, but, or, yet, so), you need a comma before the conjunction.

    Key hint:
    Cover everything after the conjunction and read it as a sentence. If it can stand alone, you need a comma plus a conjunction. If it can’t, you don’t.The SAT makes this hard by writing long second halves that feel like they need a comma but are missing a subject — so they’re not independent clauses.
    Example
    The Tantaquidgeon Museum in Uncasville, Connecticut, was founded in 1931 with the goal of showcasing the culture and history of the Mohegan ______
    today, nearly a century later, it is the oldest Native-owned and -operated museum in the country.
    A) Tribe, and  B) Tribe  C) Tribe and  D) Tribe,
    Answer: A.
    Both halves are independent clauses. You need both the comma and the conjunction. C forgets the comma. D forgets the conjunction.
    The SAT requires both.

    3. That Versus Which

    “That” introduces essential information and never takes a comma. “Which” introduces nonessential information and always requires a comma.

    Key hint:
    Remove the clause. If the sentence still makes specific sense, it’s nonessential — use “which” with a comma.
    If the sentence becomes vague or incomplete, it’s essential — use “that” with no comma.Shortcut:
    “which” can never define which one.The SAT makes this hard by writing sentences where both options sound natural, so students choose what looks right instead of testing whether the information is essential.
    Example
    In early 1700s England, it was legal for shops to sell prints of artists’ engravings without the artists’ permission.
    This changed in 1735 with the passage of the Engravers’ Copyright ______ gave engravers control over the distribution and sale of all prints made from their designs.
    A) Act, which  B) Act; which  C) Act. Which  D) Act
    Answer: A.
    The clause beginning with “which” adds information about the Act but does not define which act.
    A comma marks the boundary. B and C incorrectly break the relative clause into an independent clause.

    Form, Structure & Sense Questions

    These rules separate strong students from top scorers because the mistakes are logical, not audible.

    4. Dangling Modifiers

    An opening phrase must logically describe the subject that immediately follows it. If it doesn’t, the modifier is dangling. The SAT tests this with participial phrases, appositives, and prepositional phrases.

    Key hint:
    Read the opening phrase, then look at the subject right after the comma or dash. Ask: is this the person or thing the phrase is actually describing?The SAT makes this hard by offering answer choices that all sound reasonable — but only one puts the correct noun in the subject position.
    Example
    The Herfindahl-Hirschman Index (HHI), a commonly used measure of competition between companies in a particular market, ranges from a score of zero to 10,000 points.
    Compared with that of a highly concentrated market—that is, a market controlled by very few companies—______
    A) a market that is less concentrated will have a much lower HHI score.
    B) the HHI score of a less concentrated market will be much lower.
    C) when a market is less concentrated, its HHI score will be much lower.
    D) a less concentrated market will have an HHI score that is much lower.
    Answer: B.
    The phrase is comparing HHI scores, not markets. The subject must therefore be “the HHI score.”
    Other options sound reasonable but fail the logical comparison.

    5. Subject-Verb Agreement with Intervening Phrases

    The subject and verb must agree in number, regardless of how much material sits between them.

    Key hint:
    Cross out everything between the subject and the verb — prepositional phrases, relative clauses, parenthetical asides. What remains is what must agree.The SAT relies on students matching the verb to the nearest noun instead of the actual subject.
    Example
    In her 1983 book The Managed Heart, sociologist Arlie Russell Hochschild first explored at length her conception of a “sociology of emotions”—the idea that the various cultural and ideological frameworks a person has internalized (class, gender, political affiliation, etc.) ______ each emotional reaction that person has within a situation.
    A) underlies  B) is underlying  C) underlie  D) has been underlying
    Answer: C.
    The subject is “frameworks” — plural. But it’s buried behind “the idea that the various cultural and ideological,” and students’ ears drift to “person,” which is singular and closer to the blank. The plural verb “underlie” is correct.
    A related trap: “each” and “every”
    Key hint:
    “Each” and “every” are always singular, no matter what plural noun follows them.The SAT makes this hard by placing a plural noun right next to “each,” so the plural rings in your ear when you reach the verb.
    Although each one of these plays, which include Henry V and Richard III, ______ on a single historical figure, some feature different episodes from the same monarch’s life.
    A) focuses  B) focus  C) are focused  D) were focused
    Answer: A.
    “Each one” is always singular, even though “these plays” is right next to it. Students hear “plays” and pick the plural verb. The SAT is counting on that.

    6. Verb Tense Consistency

    When a sentence describes multiple past events, the tense must reflect their sequence. If one past event occurred before another past event, the earlier one requires the past perfect: “had + verb.”

    Key hint:
    Build the timeline. If two things happened in the past and one came first, the earlier event needs “had.”The SAT makes this hard by placing time cues early in the sentence and the verb much later, so students lose the thread and default to simple past.
    Example
    A second-generation Japanese American, Wataru Misaka ______ in World War II (1941–45) and won two amateur national basketball championships at the University of Utah when he joined the New York Knicks for the 1947–48 season.
    A) already served  B) was already serving  C) already serves  D) had already served
    Answer: D.
    Serving in World War II happened before joining the Knicks. Two past events, one earlier than the other — that’s past perfect.
    Students who pick A use simple past, which doesn’t distinguish the sequence.

  • How Score Bands Work?

     

     

    The SAT is built around 7 score levels.

    Each band tests different skills—and they build as you move up. Understanding this is the key to gaining 200+ points.

    What changes as you move up?

    Band 4 Reading asks you to find evidence that supports a straightforward claim. Band 7 asks you to find evidence that supports or refutes a claim in early college-level texts, holding two opposing ideas in mind simultaneously.

    Band 4 Algebra asks you to solve a simple linear equation in one variable. Band 7 asks you to solve systems of linear equations in two variables with symbolic representations and variable constants.

    Same test. Harder thinking.

    Why this matters for your prep

    Most practice tests mix all difficulty levels together. A student aiming for 1500+ ends up spending half their time on Band 3-4 questions they’d never miss. That’s not practice. That’s busywork.

    This is what your official score report looks like. The bars represent a Score Band Level from 1-7.

    How to break 1500

    To crack 1500, you need to master both Band 6 and Band 7 questions. Band 6 Hard questions are where good scores become great. Band 7 Extra Hard questions are where great scores become elite. Miss a few at these levels and you’re stuck in the 1400s. Nail them and you break through.

    That’s why we built Band 6-only and Band 7-only tests. No filler. Every question at the level that actually moves your score. Practice where it counts.

  • Spotlight: Brown University in the Age of AI

     

     

    While headlines about artificial intelligence in higher education tend to focus on bans, plagiarism scandals, and hand-wringing, Brown University has spent the past nine months doing something far more interesting: building an institution-wide AI infrastructure from the ground up — and appointing the leadership to steer it.

    For families navigating the college admissions landscape, Brown’s approach signals an important shift in where elite education is heading. The university isn’t treating AI as a problem to manage. It’s treating it as a core institutional capability.

     

    A New Role With Unusual Scope

    In July 2025, computer science professor Michael Littman stepped into a newly created position: Associate Provost for Artificial Intelligence. The role covers AI education, research, and responsible practices, with a charge that extends into operations and external engagement — a remit that Littman himself believes is unusually broad.

    “Other institutions have hired people to look after one or two of these areas, but I don’t know of any others that are unifying all of them in a single role,” he told Brown’s newsroom shortly after starting. He reports directly to Provost Francis J. Doyle III and leads a cross-university coordinating committee that connects academic initiatives with administrative functions.

    Littman is no bureaucratic hire. He previously served as Division Director for Information and Intelligent Systems at the National Science Foundation, where he oversaw $200 million in annual research funding and co-authored the 2023 update to the U.S. AI Research and Development Strategic Plan. He won the AAAI Outstanding Educator Award in 2024. And he earned his PhD at Brown in 1996, making his return to College Hill both a homecoming and a statement of intent.

     

    Is B-Minus the New F? What AI Means for Brown’s Academic Culture

    One of the most provocative ideas to emerge from Littman’s early work is a direct challenge to how universities grade student work. Referencing the book Teaching with AI, which his committee read together, Littman laid out a striking argument: if AI can produce C-plus or B-minus work on virtually any assignment, then perhaps that level of output simply isn’t good enough anymore.

    “Maybe a B-minus is the new F,” Littman said. “So now we have all this headroom above that where the student and the AI can work together to produce something better.”

    For Brown families, this raises a question worth thinking about — even if the university itself hasn’t posed it yet. Brown is famous for its flexible grading culture: the Satisfactory/No Credit option, no failing grades on transcripts, and a philosophy that encourages intellectual risk-taking over grade anxiety. If AI raises the baseline of what constitutes acceptable work, what does that eventually mean for a system built around generous definitions of “satisfactory”?

    To be clear, Littman hasn’t called for changes to Brown’s grading system, and the university hasn’t publicly connected his comments to S/NC policy. But the underlying tension is real: when the floor of competence rises, the institutions that have historically given students room to experiment may need to rethink what that room looks like.

     

    Free AI Tools for Every Student

    In late 2025, Brown rolled out university-wide access to AI tools — a move that puts practical technology directly into students’ hands rather than leaving them to cobble together their own subscriptions.

    Students now have free access to Google Gemini Chat and NotebookLM through their Brown accounts, cleared for the university’s highest data safety classification. The Office of Information Technology also launched Transcribe, an AI-powered transcription tool built internally through Brown’s AI Sandbox project, which Littman noted performs better and costs significantly less than commercial alternatives.

    “We think these tools are extremely relevant to the business of universities,” Littman told the Brown Daily Herald. “They shouldn’t just be available to people on campus who have their own personal resources to pay for them.”

    The OIT is also developing Librechat, a service that will consolidate multiple large language models into a single chatbot interface, giving students and faculty access to several AI models through a single Brown-managed platform.

     

    $20 Million for AI and Mental Health

    In July 2025, the National Science Foundation awarded Brown a $20 million grant to lead a new national AI institute focused on developing trustworthy AI assistants for mental and behavioural health applications. The AI Research Institute on Interaction for AI Assistants (ARIA) brings together researchers from Brown, Dartmouth, Carnegie Mellon, NYU, UC Berkeley, and several other institutions.

    Led by Brown computer scientist Ellie Pavlick, ARIA aims to build AI systems capable of context-aware, sensitive interactions with people — particularly those in states of distress. The work addresses what Pavlick calls the hardest open problems in AI today: understanding cause and effect, modelling internal human states, and building systems transparent enough to earn trust.

    “Any AI system that interacts with people, especially those who may be in states of distress or other vulnerable situations, needs a strong understanding of the human it’s interacting with,” Pavlick said.

     

    Why Interdisciplinary Matters More Than Ever

    Littman makes a compelling case that AI literacy is no longer a tech skill — it’s a research skill that cuts across every discipline. In his Q&A with Brown’s newsroom, he gave a vivid example: particle physicists are now generating more data per second than they can possibly store, so they’re using AI to filter in real time for what’s scientifically interesting. The same pattern is emerging in biology, public health, economics, environmental science, and beyond.

    This is where Brown’s open curriculum becomes a genuine strategic advantage. A student could combine cognitive science and computer science, which is exactly the intersection where the ARIA mental health institute operates. They could study how AI reshapes public policy through Brown’s new data science master’s programme, which focuses specifically on AI governance. They could explore what AI means for the humanities through the Cogut Institute’s “Models-Scale-Context” lab. Brown isn’t siloing AI into the computer science department. It’s threading it through neuroscience, engineering, applied math, public health, philosophy, and the arts.

    “AI enables people to do science more effectively,” Littman said. “We need people to be educated about what the possibilities are in AI, how it can be used, what kind of questions it can answer, and what it can’t answer.”

     

    Leapfrogging Into the Workforce

    Perhaps the most important signal for families came in Littman’s comments about the job market. He was candid: AI chatbots are already well-suited to do the kind of work companies expect from new hires, and some employers are slowing entry-level hiring as a result.

    His answer was constructive.  “Institutions like Brown need to find a way to help their graduates leapfrog over these entry-level positions and start contributing at a higher level,” he said.

    He described current AI as having “broad competence” but still lacking “deep insight.” That distinction matters. The students who thrive in the next decade won’t be the ones who can use AI tools because everyone will be able to. They’ll be the ones who understand what questions to ask, what the limitations are, and how to apply AI responsibly within a specific domain. That’s exactly what an interdisciplinary education at a place like Brown is designed to produce.

     

    What It Means for Families

    Brown’s AI strategy reflects a broader truth about where top universities are heading: the schools that will best prepare students for the next decade aren’t the ones banning AI — they’re the ones teaching students to use it critically, creatively, and responsibly.

    For prospective applicants, Brown’s investment in AI infrastructure, research leadership, and classroom integration is worth noting. It suggests an institution that sees AI fluency not as a threat to liberal education, but as an essential part of it.

    Khan Academy: Free, But Thin

    Khan Academy has been the College Board’s official SAT partner for years. The videos are solid for foundational concepts. But the practice platform hasn’t kept up with the Digital SAT.

    Where Khan Falls Short:

    • Only ~4 questions per skill. Not enough to build mastery—especially at higher score bands.
    • No gap analysis. It won’t tell you which question types are costing you points.
    • Questions skew easy. Students report content doesn’t match the harder Module 2.
    • No Bluebook interface. Doesn’t replicate the real test experience.

    Best for: Students below 1200 who need basic concepts first.

    Gemini: Free, But Broken

    Google launched SAT practice in Gemini in January 2026, partnering with Princeton Review. Free full-length tests sound great—until you actually use it.

    Where Gemini Falls Short:

    • The AI tutor is wrong more than it’s right. We tested it for 20 minutes. It gave wrong explanations 6 out of 10 times. That’s not just unhelpful—it’s detrimental. You’re learning the wrong thing.
    • Social media is full of reports of AI slop. Students are sharing screenshots of nonsense explanations and made-up rules.
    • Memory is so bad it forgets its own questions. Ask for help on a problem and Gemini asks you to provide the question. It doesn’t have the context of what it just showed you.
    • Content is old and misaligned. Princeton Review’s bank wasn’t built for the Digital SAT.
    • Can’t analyze your Bluebook scores. No way to upload results and see your gaps.

    Best for: Best for: Students who can fact-check every question and explanation themselves.

    College CoPilot: Built for 200+ Points

    College CoPilot takes a different approach. Instead of giving you more practice and hoping something sticks, it shows you exactly where your points are hiding—and builds a plan to get them.
