Learn ACT

Learn the ACT material and build the pacing to finish every section.

The ACT is a college admissions test built around English, math and reading, with a science section and a writing essay that became optional in the updated format the ACT rolled out in 2025. Questions reward speed as much as knowledge: many students know the material but run out of time. Learnr is not affiliated with ACT; it builds you a personalized course on the grammar, algebra, geometry, reading and data skills the test draws on, and lets you practice them in short sessions that build pacing alongside understanding.

How to learn ACT, step by step

Check the format and decide on the optional sections. Look up the current ACT format on the official site, and ask the colleges and scholarship programs on your list whether they want the science score or the writing essay. That decision shapes which sections you prepare for.
Take a timed official practice test. Use an official ACT practice test with strict timing. Note both which questions you missed and where you ran out of time, because pacing problems and knowledge gaps need different fixes.
Master commas and the other English rules. ACT English tests a recurring set of rules: commas around nonessential clauses, run-ons and fragments, apostrophes, modifier placement and wordiness. When two answers are both grammatical, the shorter clear one is often right, so practice cutting redundant words.
Cover the full math range, not just algebra. ACT math reaches past algebra into plane and coordinate geometry, basic trigonometry, probability and statistics. Build your own formula sheet for areas, volumes, SOHCAHTOA and slope, since the test expects you to know these from memory.
Practice reading for location, not memory. Skim each passage for its structure, then go straight to the lines a question points to. Practice paired passages and keep moving, because rereading a whole passage for one detail is where most Reading time disappears.
Treat science passages as data problems. If you take science, most questions ask you to read graphs, tables and experimental setups rather than recall facts. Practice identifying the variables, the trend, and what changed between one experiment and the next.
Practice in short timed sets every day. Short timed drills build the speed the ACT demands. A Learnr course gives you daily bite-sized practice and a streak to keep momentum between full practice tests.

What's inside your ACT course

A sample path Learnr builds for ACT. Your real course adapts to your goal and level.

1. How the current ACT is structured
2. English: punctuation, grammar and rhetorical skills
3. Math: pre-algebra through trigonometry
4. Reading: passage strategies and question types
5. Science: data representation and experiments
6. Pacing, guessing and test-day strategy

How long does it take to learn ACT?

A focused review usually takes 1 to 3 months at 3 to 6 hours a week. If math through trigonometry or fast reading is new territory, plan for longer. Pacing tends to be the slowest skill to build, so leave room for several timed practice tests.

What you need before you start

High school English plus math through Algebra 2 and some trigonometry. No earlier test prep is needed, but steady reading habits help you keep up with the pace of the Reading section.

Common mistakes to avoid

Leaving questions blank when time runs out. The ACT does not penalize wrong answers, so fill in a guess for anything you cannot finish.
Studying content without ever timing yourself. Many students understand the material yet lose points by running out of time, so time most practice sets.
Picking the longest, most formal-sounding option in English. The ACT usually prefers concise, clear wording when every choice is grammatical.

ACT questions, answered

Should I take the SAT or the ACT?

Most US colleges accept either. Take an official practice test of each, compare how comfortable you feel with the pacing and question styles, then focus your prep on one.

Is the ACT science section required?

In the updated ACT format, science is optional, as is the writing essay. Some colleges or scholarship programs may still ask for them, so check their requirements and the official ACT website before you register.

Is Learnr official ACT prep?

No. Learnr is not affiliated with ACT and makes no claims about scores. It teaches and drills the underlying English, math, reading and science reasoning skills.
