How these exams are actually built, and what that costs you
Strategy for the digital SAT and ACT: the wrong-answer traps, what changed on each exam, and how to review a practice test.
We audited our own question bank. Here is what was wrong with it.
We stripped the answer keys off our own question bank and had every question solved again from scratch. Here is what came back broken, and what a bad practice question looks like from the inside.

How wrong answers are built
One page per wrong-answer pattern: what it is, how to spot it, how to beat it, and how often it shows up in our question bank.
Inside our question bank6
- Practice questions expire, and an expired one looks exactly like a good one
The SAT and ACT both changed format recently, and questions written for the old versions still circulate. Three checks you can run on your own material in under a minute, and why a question bank has to be re-examined rather than built once.
- Hard SAT practice tests: what makes a question hard, and why we serve fewer of them
An all-hard form answers one question: is the difficulty the problem, or is it something else? What earns a question a hard label, why the Math gauntlet throws its own score away, and why there are fewer hard forms than standard ones.
- We ask you one question after a wrong answer, and it is not about the content
Every wrong answer in the app offers four buttons: fell for the trap, careless slip, didn't know it, ran out of time. Here is the reasoning behind building that, and what it cannot do.
- We counted the wrong answers in our ACT Reading bank. Two kinds dominate.
Of 2,890 wrong answers we gave a pattern name in our own ACT Reading questions, 38 percent are just two kinds. The second one surprised us, and the counts come with real limits.
- Only 2.6 percent of the wrong answers in our ACT Math bank are arithmetic
We labelled 1,138 wrong answers in our own ACT Math questions. Thirty are plain arithmetic. The largest group, at 21 percent, swaps one rule or definition for a neighbouring one.
- In our ACT English bank, rule-breaking and judgment are now an even split
We gave a pattern name to 2,453 wrong answers in our own ACT English questions. Mechanics account for 39 percent and judgment for 51 percent. Preparation that covers only rules misses the larger half of what the section asks.
How the tests work now14
- Your free SAT score sends close before you see your score
When you registered you could pick four colleges to get your scores for free. Those reports go out on their own, and the deadline to change your mind lands before you find out how you did.
- Did the enhanced ACT get harder? ACT measured it, and published the answer
Slightly, especially in Reading, and the difference is small enough that equating absorbs it. What did change is how much a single question is worth and how precise your score is.
- The ACT photo deadline lands after registration closes
ACT cancels a paid registration if no photo is uploaded by its deadline, which falls after registration closes; here is the September 19 timeline, ACT's own wording, and the $49 date change option.
- The paper SAT exists, but its request deadline comes early
College Board still offers a paper SAT for students whose documented disability prevents computer testing, but approval can take up to seven weeks and each test date has its own request deadline.
- The SAT device loan deadline arrives before registration closes
The deadline to borrow a device closes 30 days before test day, weeks before registration itself closes. That gap catches people who sign up late and find the loaner programme already shut.
- A miss in the first module costs more than a miss in the second
On the digital SAT, how you do in the first part of a section decides which second part you get, and that decides the top score still available to you. Same number of misses, different score, depending only on where they happened.
- AP Statistics drops five topics before the May 2027 exam
The revised AP Statistics course drops five topics before the May 2027 exam, including chi-square goodness of fit and slope inference, so older practice materials need checking against the new topic list.
- A pending ACT Writing score can hold back your whole report
ACT holds a test date's official score report until every score from that sitting is ready, so a pending Writing essay can delay everything colleges receive; plan test dates and self-reporting backups around that rule.
- ACT superscores now use English, Math and Reading, not Science
ACT's superscore takes your highest English, Math and Reading from any sitting, legacy or enhanced, excludes Science, and is built automatically. What that means for scores you already have.
- The enhanced ACT composite is three sections now. What that changes, and what it doesn't.
Since 2025 the ACT composite is the average of English, Math, and Reading, with Science optional and never counted. That has produced a lot of confused advice. Here is what it actually means.
- The enhanced ACT in 2026: what actually changed
The ACT is shorter now, Science is optional, and Math has four answer choices instead of five. Here is exactly what changed and how to adjust your prep.
- How the digital SAT's adaptive second module really works
Each SAT section has two modules, and the first decides the second. Understanding the routing changes how you should pace the test, especially the first module.
- What actually changed on the digital SAT (and what it means for how you practice)
The SAT went fully digital and adaptive. The format changes get all the attention, but the real shift is in what the questions test. Here is what changed and how to adjust.
- SAT or ACT: how to decide in a weekend
Colleges accept both equally, so the only question that matters is which one you score higher on. Here is how the two exams actually differ and a simple side-by-side test to settle it.
Admissions and policy14
- Should you register for the September SAT before your August score arrives?
September registration closes August 28 and your August score does not arrive until September 4. You can still avoid deciding blind, and the way to do it is not the one most people reach for.
- Universities stopped detecting AI essays. They changed the format instead.
Detectors are being switched off because they misfire on careful, plain writing. What replaced them asks you to show a decision rather than a finished text, and that changes what is worth practising.
- SAT and ACT fee waivers for 2026-27: what each one covers and who qualifies
Both exams are free twice if you qualify, and the waiver covers more than the test. What each includes, the eligibility criteria as the boards write them, and how to get one.
- Should you retake the ACT on September 19? Late registration closes September 1
The next ACT is about a month out and late registration closes September 1. How to decide using your section spread and your colleges' superscore policies, rather than a feeling about your composite.
- Every deadline for the September 19 ACT, and what happens if you miss one
Late registration runs to September 1, the photo upload to September 14, and scores start arriving October 6. The four dates that matter for the September 2026 ACT, and what each one actually cuts off.
- Choosing a Common App essay topic when nothing has happened to you
The prompt matters less than you think, the dramatic story is usually the weaker one, and there is a real line between honest and too personal. How to pick a subject you can actually write 650 words about.
- Common App activity hours: what to enter for hours per week and weeks per year
What to put in the two number fields when your schedule is irregular, your season is short, or the form asks about your busiest weeks. Plus how to choose and order the ten rows.
- Need an SAT score by November 1? October 3 is your last weekend test
October 3 scores are scheduled for October 16, sixteen days before a November 1 deadline. November 7 scores land nineteen days after it. What that leaves you to decide, and when each college makes an exception.
- What survives the Common App rollover on August 1, and what does not
Learn exactly which parts of your Common App account roll over on August 1 and which sections the system wipes clean.
- Your $10 AP free-response copy arrives with no feedback
College Board sells a $10 copy of your AP free-response answers, delivered with no comments, no per-question scores, and no path to a rescore or appeal; its only real use is review with a teacher.
- The retake gap: what superscoring quietly rewards
Most selective colleges superscore, which rewards taking the test more than once. New research shows universal testing gives equal access to a first score, not a competitive one. Here is what to do about it.
- The test-optional era is ending: where the Ivy League stands for 2026-2027
Six of the eight Ivies require the SAT or ACT again for the 2026-2027 cycle, and the last two are close behind. Here is the current state and what it means if you are applying.
- Why National Merit cutoffs dropped for 2027 (it is not a harder test)
The Class of 2027 National Merit cutoffs fell, and the panic online is misreading it. The likeliest cause, per the analysts who track this, is that 2026's cutoffs were inflated by a digital PSAT scaling issue. Here is what actually happened.
- AI is flattening the college essay. Here is what that does to your test score.
As AI makes application essays sound more alike, a proctored SAT or ACT score carries more independent signal. That is not proof testing is fair, but it changes whether to submit one.
Test logistics1
- ACT reused Math questions across its four practice tests, and the repeats do not count
Six Math questions in the official practice tests appear twice. Every repeat sits in a Not Scored cell, so it never enters your raw score. What that means for using these tests, and the one thing you should not try to memorise.
