Which Test Should You Take?

Most high school juniors take the SAT or ACT to include with their college applications, and oftentimes have no idea which test they should take. Here are the most important factors to consider when deciding which test will be the best for you.

Test Length

Both tests are similar in length, and both have an optional writing section. While some universities do not require the writing section of the SAT or ACT, most “recommend” it. Since you must sit through (and pay for) the entire test in order to take the essay, it’s a good idea to complete the essay at least the first time you take the test. Click here for a list of colleges that require the writing/essay section of the New SAT and ACT.

  • 3 hours 50 minutes (with Essay)
  • 3 hours (without Essay)
  • 3 hours 30 minutes
    (with Writing)
  • 2 hours 50 minutes
    (without Writing)


Without their respective essays, the SAT covers three categories over four sections, while the ACT covers four categories. The ACT has a Science section, but does not require a comprehensive knowledge of Chemistry or Biology; instead, the test assesses your analytical and problem solving abilities. Though the New SAT is more straightforward and in line with the high school curriculum than it used to be, the ACT is still more straightforward in the wording of its questions.

  • Critical Reading – comprehension, vocabulary in context, use of evidence
  • Writing – grammar, usage
  • Mathematics – mostly Arithmetic, Algebra, and Geometry, with a limited amount of Algebra II and Trigonometry. Calculator and No Calculator sections. Formula sheet provided.
  • English – writing, grammar, usage, rhetorical skills
  • Mathematics – mostly Arithmetic, Algebra, and Geometry, with a limited amount of Algebra II and Trigonometry. Calculator permitted on the whole test. No formula sheet.
  • Reading – comprehension
  • Science – data interpretation, analysis, problem solving

Scoring/Guessing Penalty

Colleges tend to look at the individual sections of the SAT more closely than the ACT. The New SAT now divides scores into several sub-scores and cross-test scores, but it’s unclear how much colleges will look at these.

For the ACT, colleges tend to focus most on the composite score. That means that even if you do poorly on one section, if you do well enough on the other sections, you can still end up with a strong composite score.

Neither the New SAT nor the ACT have a guessing penalty, which means that you should guess on every question and leave no question unanswered.

  • Total – 1600
    (sum of 2 below)
  • Evidence-based Reading and Writing – 800
  • Mathematics – 800
  • Optional Essay – 3 scores of 2-8
  • Composite- 36
    (avg of 4 below)
  • English + Writing – 36
  • Math – 36
  • Reading – 36
  • Science – 36
  • Optional Writing score of 2-12

Use By Colleges

Both the SAT and ACT are accepted by all four-year colleges and universities in the United States.

Similarity to PSAT

If you are aiming for a top score in hopes of becoming a National Merit Scholar, you will need to prepare for the PSAT, which is very similar to the SAT. If, however, you had a difficult time with the PSAT, you might want to try out the ACT as an alternative.


If you have trouble finishing the test on time and do not receive an extended time accommodation, the New SAT may be the better choice because it is a little slower paced. The following chart shows the time per question for each section, which includes reading (or skimming) the passages. Even while adjusting for differences between the length and complexity of the passages and questions, you can see that the ACT is faster paced:

Equivalent Sections SAT ACT
ACT English, SAT Writing and Language 45 sec/question 30 sec/question
Reading 75 sec/question 50 sec/question
Mathematics (Calculator) 90 sec/question 60 sec/question
Mathematics (No Calculator) 75 sec/question N/A
Science N/A 50 sec/question
Optional SAT Essay / Optional ACT Writing 50 minutes 40 minutes

Extended Time Accommodation

While the SAT allows more time per question, the ACT may be a better choice for students with an extended time accommodation because of the way accommodations are delivered. During the SAT, students with 50% extended time can only complete one section at a time and must stay on the same timeline as the rest of the extended time group. Students who receive 50% extended time on the ACT, however, are given an extended block of time for the entire test and then allowed to self-pace, dividing their time between sections as they see fit. Students who qualify for 100% extended time can take the SAT over two days at their school, while students who qualify for 100% extended time on the ACT can take one section per day at their school.

The SAT has one extra testing date for the rest of the scholastic year compared to the ACT. However, it is important to consider which SAT Subject Tests you will be taking since they are only offered on certain dates.

Computer-based Testing

Neither the SAT nor ACT offers a computerized version of the test for all students. The SAT only offers use of a word processor on the essay for students with a special accommodation. For eligibility requirements, click here. The ACT has a pilot program for computer-based testing that it will be expanding this year, but the computerized test will most likely only be offered to a select number of schools.

  • Only for students who require special accommodation
  • Select schools only


The traits listed in the chart below can help you determine which test to take, but the most effective way to determine which test is best for you is to take a full-length practice exam for both the SAT and ACT and then compare the scores.
