The ACT: Sections, Scoring, and How It Compares to the Digital SAT

The ACT went through its biggest update in years with the enhanced format. This guide covers the sections, the timing, how the Composite score is built, and how the ACT stacks up against the Digital SAT, so you can decide which test fits you.

The enhanced ACT: what changed

Recent ACT test dates use an updated, "enhanced" format. The headline changes:

• Science is now optional. The core test is English, Math, and Reading.
• The core test is shorter. The three required sections run about 2 hours, with fewer questions and a bit more time per question.
• Math has four answer choices instead of five.
• The optional Writing (essay) is still available and is scored separately.

The ACT is offered both on paper and online. Whichever way you take it, the ACT is not adaptive. Everyone answers the same set of questions, unlike the section-adaptive Digital SAT.

The sections at a glance

Adding Science brings the multiple-choice testing time to about 2 hours 45 minutes. The essay, if you take it, is separate from the multiple-choice sections.

How the ACT is scored

Each section is scored on a 1 to 36 scale. Your Composite score, also 1 to 36, is the average of your required section scores (English, Math, and Reading), rounded to the nearest whole number. A few things to know:

• Science is reported separately. If you take it, you get a 1 to 36 Science score, but it does not factor into the Composite.
• STEM score. When you take both Math and Science, you also get a STEM score that averages those two.
• Writing is separate. The essay is scored on its own scale and does not change your Composite.
• No penalty for wrong answers. You are scored on correct answers only, so answer every question, even if you have to guess.

Should you take the Science section?

Because Science is optional, whether to take it depends on where you are applying. Some colleges and scholarship programs, and many STEM-focused paths, still like to see a Science score or a STEM score. If a school you care about recommends it, or you are strong at reading charts and interpreting experiments, taking Science can only add information. If you are unsure, check the testing requirements for your target schools before you register.

Digital SAT vs ACT: a side-by-side comparison

Which one should you take?

Neither test is universally "easier," and colleges that require testing accept both equally. A few honest rules of thumb:

• The ACT tends to reward a fast, steady pace and gives you a clean way to skip a dedicated Science section if you do not need it.
• The Digital SAT is shorter per question and adapts to you, and its Reading and Writing questions come in short, focused chunks.
• The best way to choose is to take a timed practice test of each under real conditions and see which format feels more natural. Then commit to that one and prepare deliberately.
