About this exam

The ACT is a college admissions test taken by high school students and used by U.S. colleges in admissions and scholarship decisions. According to ACT, more than two million students take it each year and all U.S. colleges accept it. The core exam covers English, math, reading, and science, and ACT describes the science and writing sections as optional add-ons that do not affect your Composite score. Students choose between digital and paper testing. Timing is tight: English gives you 35 minutes for 50 questions, math 50 minutes for 45 questions, reading 40 minutes for 36 questions, the optional science add-on 40 minutes for 40 questions, and the optional writing add-on 40 minutes for one prompt. The base test fee is $70.00, with a $25.00 writing add-on and a $5.00 science add-on; fee waivers are available to those who qualify. Preparation is straightforward: ACT offers free practice tests, sample questions, and study guides, plus paid classes and tutoring. A sensible plan is to take a full-length practice test early, compare section scores against your target, and drill your weakest section under real time limits before registering.

Common questions

About ACT preparation

How long is the ACT and how many questions are on it?

Per ACT, English is 35 minutes for 50 questions, math is 50 minutes for 45 questions, and reading is 40 minutes for 36 questions. The optional science add-on is 40 minutes for 40 questions, and the optional writing add-on is 40 minutes for one prompt. Check your own registration for the total seat time.

Are science and writing required?

No. ACT states that the science and writing sections are optional add-ons and do not affect your Composite score. You choose whether to add them when you register, so skip them unless a college or scholarship you care about wants them.

What does the ACT cost?

ACT lists the base test at $70.00, the writing add-on at $25.00, and the science add-on at $5.00. ACT also notes fee waivers are available to those who qualify based on location and household income, so check eligibility before you pay.

Can I take the ACT online or on paper?

ACT says you can test the way you test best: digital or paper. Both options cover the same content. If you test digitally with your own device, ACT advises bringing a fully charged laptop and charger on test day.

What should I bring on test day?

ACT's checklist includes your admission ticket printed from MyACT after uploading a photo, an acceptable photo ID, sharpened No. 2 pencils with erasers, a watch with no alarm, snacks for breaks, and a permitted calculator for the math test only. Bring a fully charged device and charger if testing on your own laptop.

How hard is the ACT?

Difficulty is mostly about pace, not trick questions. ACT describes the test as built on what you learned in class, with no tricks and no adaptive surprises. The math section assumes skills typically acquired through courses up to the beginning of grade 12, so gaps in algebra or geometry hurt more than unfamiliar content.

How should I structure my prep?

Start with a free full-length practice test from ACT to get a baseline. Then spend most of your time on the section with the largest gap to your target score, practicing under the official time limits. Finish with timed full sections so pacing, not content, is the last thing you fix.

What are the most common mistakes test takers make?

Running out of time is the big one, since each section is tightly timed. Others include skipping the optional sections without checking whether a target college wants them, forgetting the admission ticket or acceptable photo ID, and bringing a calculator that is not permitted. ACT advises reviewing its full test day guidelines in advance.

When are upcoming ACT test dates and deadlines?

ACT lists December 12 with a November 6 registration deadline and November 29 late registration, and February 27 with a January 22 deadline and February 9 late registration. A late fee applies. ACT also notes no test centers are scheduled in New York for the July test date.
