Last-Minute ACT Tips: What the Final Week Can Actually Move

Updated · 10 min read

Most advice about the last week before the ACT is either useless ("get a good night's sleep") or dishonest ("raise your score 5 points in 7 days"). Both avoid the only question worth asking, which is what a week can actually change.

Some things can. A week is enough to memorise the comma rules, learn the handful of formulas the Math section reuses, and build a pacing plan that stops you losing six questions to the clock. Other things cannot. A week will not make you a faster reader or close a two-year content gap, and any plan that assumes it will is going to waste the week you have.

The final week moves rules and pacing, not knowledge. English grammar rules and a timing strategy are learnable in seven days and worth real points. Reading speed and broad content fluency are not. Plan for one or two points, not five.

First, the pacing numbers nobody gives you

Almost every last-minute mistake is a clock mistake, and you cannot manage a clock you have not counted. Here is the Enhanced ACT, as seconds per question:

SectionQuestionsMinutesSeconds per question
English503542
Math455067
Reading364067
Science404060

English is the tightest clock on the test by a wide margin — 42 seconds, against 67 in Math and Reading. That is the single most useful number in this article, because almost nobody discovers it until they are 15 questions from the end with four minutes left.

What to do with it: pick a checkpoint. In English you should be at question 25 with 17 minutes gone. In Reading you should have finished your second passage at the 20-minute mark. Knowing one checkpoint per section converts a vague sense of panic into a decision you can make at a specific moment.

Each section also contains unscored field-test questions that look exactly like the real ones — 10 of the 50 in English, 9 of the 36 in Reading. You cannot identify them and you should not try. Their only practical consequence is that a question that feels impossible may simply not count, which is a reason to move on rather than to dig in.

English is where a week actually pays

If you only have time for one section, it is this one, and not because it is the most important. It is because English is the most rule-bound section on the test. A small, fixed, memorisable set of rules generates most of the questions, which means something you learn on Tuesday is worth points on Saturday. That is not true of any other section.

The rules worth having by test day:

  1. Commas. Independent clause + comma + coordinating conjunction + independent clause. Non-essential information in a pair of commas. No comma between a subject and its verb. Most comma questions on the test are one of these three.
  2. Semicolons and colons. A semicolon joins two complete sentences — which means it is interchangeable with a period, and that is the test's favourite trap. A colon needs a complete sentence before it, never after.
  3. Apostrophes. Its versus it's, their versus they're, plural possessives. Mechanical, frequently tested, easy to get right every time.
  4. Subject–verb agreement across a phrase. "The box of nails is" — the test's standard move is to put distance between the subject and the verb so your ear agrees with the nearest noun.
  5. Shortest answer wins, usually. When two options are both grammatically correct, the ACT prefers the concise one. "DELETE the underlined portion" is right more often than students expect.

That list is a few hours of work and it is the highest-yield few hours available to you this week.

Math: the formulas, not the concepts

You are not going to learn new mathematics this week. You can make sure you are not losing points to a formula you simply do not have in front of you — the ACT gives you no formula sheet.

Worth writing out from memory until it is automatic: the area and circumference of a circle, the Pythagorean theorem and the two special right triangles (30-60-90 and 45-45-90), slope and the equation of a line, the quadratic formula, the distance and midpoint formulas, SOHCAHTOA, arithmetic and geometric sequences, and the laws of exponents.

Two habits that are worth more than another topic:

  • Plug in the answers. Multiple choice means the answer is on the page. On an algebra question you cannot see your way through, substituting the options is often faster than solving — and it cannot be wrong.
  • Read what is actually being asked. The most common Math error on a timed test is solving correctly for x when the question asked for 2x. At 67 seconds a question there is time to re-read the last line.

Reading and Science: strategy, not content

Neither of these rewards cramming, because neither tests anything you could memorise. What they reward is a decision made in advance about how you will spend the time.

For Reading, at 67 seconds a question across four passages, the thing to settle before test day is your order. If one passage type reliably costs you time — for most people it is the one with paired texts — do it last. Finishing three passages well beats starting four badly.

For Science, the honest advice is different, and it is the one piece of last-minute advice on this page that nobody else will give you.

On the Enhanced ACT, Science is optional and does not count toward your composite. The composite is the average of English, Math and Reading only. If no college on your list requires or recommends Science and your final week is short, that is the section to let go.

Check your colleges before you act on that — some programmes, particularly in engineering and the health sciences, still ask for it. But if none of yours does, you have just recovered 40 minutes of preparation time and a section's worth of test-day fatigue, and your composite is unaffected.

The same change has a sharper edge: with three sections in the composite instead of four, one weak section now carries a third of your score rather than a quarter. Your worst scored section matters more than it used to.

The day before

Do less than you want to.

  • One timed section, not a full test. You are staying warm, not training. A full practice test the day before costs more in fatigue than it returns in readiness.
  • Re-read your own mistakes, not new material. The questions you have already got wrong are the only ones that have told you something.
  • Pack the night before: admission ticket, photo ID, approved calculator with working batteries, several sharpened pencils, a watch without a smart display, a snack and water.
  • Check the centre and the drive. Test centres fill up, so a late registration often means an unfamiliar journey. Find out how long it takes before the morning you have to do it.
  • Sleep. Dull, and it is the single most reliable intervention available to you at this point.

The timing reality check nobody does

One thing worth doing before you spend the week panicking, because it may change what you are panicking about: work out whether the score from this sitting will arrive in time to matter.

ACT publishes a window of one to four weeks for score release. Plan against four. A score from the December sitting typically lands in early January — which is after most December 1 and January 1 scholarship priority deadlines have already closed.

So if your last-minute preparation is aimed at a merit deadline, check the arithmetic first. Every sitting's score release window is worked out date by date here, and the full test date and deadline schedule is here. If the score cannot arrive in time, the right move is not a harder week — it is registering for the next date and preparing properly.

And it is worth knowing what the points are actually worth before you chase them. One point near the national average of 19.1 clears another 5% of the field; one point from a 33 to a 34 clears 1%, and one from a 34 to a 35 clears nothing at all — both report the same percentile. In scholarship terms the picture is almost reversed, because published merit grids sit on round thresholds rather than rising smoothly — so a point either crosses a band and is worth thousands, or it changes nothing at all.

Find out which points are actually reachable

About three minutes, no account. You see a projected score for every section and the specific concepts costing you the most — which is the only way a short week gets spent on the right thing.

What not to do with the last week

  • Do not re-read chapters you already understand. This is where most final weeks go, it feels productive, and it changes nothing. The points are in the questions you get wrong.
  • Do not start new material. Anything you begin this week you will half-know on test day, and a half-known rule is worse than no rule because you will trust it.
  • Do not take a full test the day before. See above.
  • Do not change your calculator. Test day is not the moment to learn a new interface.
  • Do not grind practice questions without reading the explanations. A question you got wrong and did not understand has taught you nothing. This is the whole difference between doing practice and getting better: an answer key tells you that you missed it, and only an explanation tells you why.

That last one is the real distinction between a free PDF and useful preparation, and it is worth being blunt about. Official practice tests are free and you should use them. What they give you is an answer key. What a short week needs is the reason — because with seven days left, the only thing worth knowing is which specific misunderstanding is costing you points, and a letter in a margin cannot tell you that.

Frequently asked questions

What are the best last-minute ACT tips?

Work on pacing and on rules, not on knowledge. English is 42 seconds a question and is the most rule-bound section on the test, so grammar rules you memorise this week will show up next week. Reading and Science are 67 and 60 seconds a question and reward a timing strategy rather than new content. And if you are short on time, Science is the section to drop: on the Enhanced ACT it is optional and does not count toward your composite.

Can you improve your ACT score in a week?

In places, yes. Comma and semicolon rules, the handful of geometry formulas the test reuses, and a pacing plan are all learnable in a week and all worth real points. What a week will not do is build reading speed or close a broad content gap — those move over months. Expect a point or two from a well-spent final week, not five.

What should I do the day before the ACT?

Nothing new. Do one timed section to stay warm, re-read the mistakes you have already made rather than attempting fresh material, pack your admission ticket, photo ID, approved calculator and pencils, and sleep. A full practice test the day before costs you more in fatigue than it gains you in preparation.

How many seconds per question do you get on the ACT?

On the Enhanced ACT: 42 seconds a question in English (50 questions in 35 minutes), 67 seconds in Math (45 in 50 minutes), 67 seconds in Reading (36 in 40 minutes) and 60 seconds in Science (40 in 40 minutes). English is the tightest clock on the test and the section where pacing failure is most common.

Should I skip the Science section on the ACT?

On the Enhanced ACT, Science is optional and sits outside the composite — the composite is the average of English, Math and Reading only. If a college on your list requires or recommends Science, take it. If none does and your final week is short, the time is better spent on a section that counts toward the number colleges actually read.

Is it worth cramming for the ACT?

Cramming content is not worth it. Cramming rules and pacing is. The distinction matters: the test reuses a small, fixed set of grammar rules and formulas that reward memorisation in a week, while reading comprehension and broad maths fluency do not respond to a week of effort at all.

What should I not do the week before the ACT?

Do not take a full practice test the day before, do not start new material, and do not re-read chapters you already understand — which is where most of the final week actually goes. Re-reading what you know feels like studying and changes nothing, because the points are in the questions you get wrong.
