How to Study for the ACT: A Plan Built on Practice Tests

By Zeynep AksoyReviewed by Elif KorkmazPublished

Study for the ACT by measuring first and studying second. Take a timed, full-length practice test, use it to find the section skills that cost you the most points, spend most of your study time there, and check your progress with further full-length tests spaced a few weeks apart. Everything below turns that idea into a plan for the enhanced ACT.

Know the test you are studying for

ACT has revised the test — it calls the new version the enhanced ACT — so make sure your plan matches it. According to ACT, the test looks like this:

SectionTimeQuestionsStatus
English35 minutes50Required
Math50 minutes45Required
Reading40 minutes36Required
Science40 minutes40Optional add-on
Writing40 minutes1 promptOptional add-on

Science and writing do not affect your Composite score, which since September 2025 has been based only on English, math and reading. Section scores are reported on a 1–36 scale. If you take science, you also receive a science score and a STEM score. Decide early whether you will sit the optional sections — check what the colleges and programmes on your list ask for — because that decision changes how many sections you need to prepare. The official ACT test page lists the format and upcoming test dates.

Step 1: Take a timed diagnostic

Start with a complete practice test under real timing, in one sitting, before you open a book. ACT offers four official full-length practice tests free of charge, each available digitally, with timed and untimed versions of every section, or as a printable booklet, and a scoring key converts your raw score. A diagnostic taken without timing tells you what you know; a timed one also tells you what you can do in the time available, which is what the score depends on.

Step 2: Read the result by section and by type of mistake

A section score shows where you lost points; the questions themselves show why. Go through every miss and label it:

  • Content gap — you did not know the rule, formula or concept.
  • Misreading — you knew the material but answered a different question from the one asked.
  • Time pressure — you rushed, guessed or never reached the question.
  • Careless slip — an arithmetic or copying error on a question you could do.

Each label calls for different work. Content gaps need study; misreadings need slower, more deliberate reading of the question; time pressure needs timed section practice; careless slips need a checking routine.

Step 3: Study section by section

The timing per question differs sharply between sections, so it helps to know the pace each one demands:

  • English (about 42 seconds per question). ACT describes it as making decisions to revise and edit short texts and essays in different genres. Learn the punctuation, sentence-structure and usage rules, and practise the questions that ask whether a sentence belongs in a paragraph or serves the writer's purpose.
  • Math (about 67 seconds per question). It measures the skills students typically acquire in courses up to the beginning of grade 12. Rebuild weak topics from worked examples, then practise mixed sets, because the test does not tell you which topic a question belongs to. ACT's free calculator help videos are worth watching if you are unsure of your own calculator.
  • Reading (about 67 seconds per question). It measures your ability to read closely, reason logically and integrate information from more than one source. Practise reading for the author's point and structure, and train yourself to find the line that justifies each answer.
  • Science, if you take it (about 60 seconds per question). It measures interpretation, analysis, reasoning and problem-solving in biology, chemistry and Earth and space sciences. Much of the work is reading graphs, tables and experimental set-ups quickly and accurately.
  • Writing, if you take it (40 minutes for one prompt). ACT says it measures writing skills taught in high school English classes and entry-level college composition courses. Practise planning and writing a complete response within 40 minutes; each official practice test includes a writing prompt.

Step 4: Choose your books and materials

After the free official tests, ACT's own books are the natural next step, because they are written by the test's makers. The Official ACT Prep Guide 2026–2027 contains four full-length tests, all including the optional writing test, with explanations for every answer, tips for each section and advice on preparing for test day. ACT's Official Subject Guides for English, math, reading and science (third edition, 2026–2027) teach one section at a time, and each comes with an access code for a year of online practice questions. The official guides page lists what each contains.

If you consider any other book, check three things before relying on it: that it reflects the question counts and timing shown above, that it treats science and writing as optional, and that every practice question comes with a full explanation. A book built around the older, longer ACT will train the wrong pacing.

Step 5: Build a weekly rhythm

A rhythm you can keep beats an ambitious plan you abandon. A typical week might include:

  1. Two or three focused sessions on your weakest section, each ending with a short timed set.
  2. One session on your second-weakest section.
  3. One timed section under full test conditions, rotating through the sections from week to week.
  4. A review session for everything you got wrong that week, with the mistake labels from Step 2.

Free daily practice helps too: ACT offers practice by section, a short-quiz tool and a question of the day for MyACT account holders.

Step 6: Retest, review, repeat

Take a full-length test every two to three weeks rather than every weekend. A full test costs an afternoon, and its real value comes from the review that follows; a test that is never reviewed teaches almost nothing. In the final month, shift the balance towards timed full tests, because pacing and stamina then matter more than new content. Compare section scores across tests rather than reacting to a single result, and adjust the weekly rhythm whenever a section stops improving.

Where NewEducare's ACT practice fits

When the official tests run out, or you want more timed practice between them, NewEducare's ACT practice tests are timed to ACT's official section limits, with a worked explanation for every question and a report by section, topic and timing. The free full-length ACT diagnostic test includes all five sections, the optional science and writing as well as English, math and reading, and needs an account but no payment. When you know which section needs work, the ACT practice tests and question bank let you practise by section, topic and difficulty. NewEducare is independent of ACT, and its questions are written to the published specification rather than taken from real tests.

Frequently asked questions

How long should I study for the ACT?
Work back from your test date. Leave room for at least three full-length practice tests spaced two to three weeks apart, with focused study and review in between. Those tests alone span four to six weeks, so start at least two months before your test date, and earlier if the diagnostic shows a large gap to your target.
Do I have to take the ACT science test?
No. On the enhanced ACT, science and writing are optional add-ons and do not affect your Composite score. If you take science, you also receive a science score and a STEM score. Check whether the colleges or programmes you are applying to ask for either section before you register.
What are the best ACT prep books?
Start with ACT's own material: the free official practice tests, then The Official ACT Prep Guide, which contains four full-length tests with explanations for every answer. For any other book, check that it reflects the enhanced ACT's question counts and timing and treats science and writing as optional.
Are the free official ACT practice tests enough?
They are the best place to start, and ACT offers four of them, digital or paper. If you plan more than four full-length tests, or want to drill one section in depth, you will need further practice material.
How is the ACT Composite score calculated?
Since September 2025, the Composite on all ACT tests is based only on English, math and reading. Section scores are reported on a 1–36 scale, and science, if you take it, is reported separately.
