Deciding on the  

Figuring out whether to take the SAT or ACT can feel like a big decision. But not to worry! Here is some information to help you decide on the test that is the best fit for you. Both tests are accepted by all colleges and universities across the country, so the decision comes down to your own personal preference and whichever test you believe you will do better on. 

Let’s take a look at some of the similarities between the two tests. Then we’ll look at the major differences between them, and finally, how to choose the right one for you.

Similarities Between Both Tests:

Differences Between Both Tests:

Here we will break down how each test differs in formatting, question type, and content.

I. Sections:

The SAT has 3 sections: Reading, Math, & Writing/Language

The ACT has 4 sections: Reading, English, Math, & Science (+ optional essay)

II. Total Number of Questions:

SAT: 151 questions total

ACT: 216 questions total

III. Time Limit:

SAT: The SAT has 3 tests and a total time limit of 3 hours. The sections are longer, but there are fewer of them, which means you have more time to work on each question.

ACT: The ACT has 4 tests and an optional essay. The total time is 2 hours and 55 minutes for the full test, plus an additional 40 minutes if you choose to do the essay. ACT sections are shorter, but there are more of them, so you must work at a quicker pace to get through the full test. 

☆ SAT pro: if you prefer more time on questions and/or struggle with time management on tests
IV. Scoring:

SAT: scores range from 400-1600

ACT: scores range from 1-36

How Much Does the SAT Cost?

Sections Breakdown:

✔︎ The ACT has a Science section, the SAT does not.

ACT Science makes up ¼ of your total score. The SAT has questions on scientific concepts throughout its test but does not have a full section on it. (The SAT also has an “Analysis in Science” sub-score, however, schools don’t really pay attention to subscores.)

☆ ACT pro: if you excel in science!
✔︎ SAT Math has a “No Calculator” section, ACT Math allows you to use a calculator throughout the whole test. 

This section is only 25 minutes long and is the shortest section on the SAT.

☆ SAT pro: if you are good at mental math and can solve equations quickly without a calculator
☆ ACT pro: if you are not good at mental math
✔︎ The SAT provides math formulas.

You don’t need to memorize as many formulas for the SAT versus the ACT where you must memorize all math formulas. (Note: This is because the ACT focuses more on what is learned in high school, whereas the SAT focuses more on applying those concepts to real-world scenarios.)

☆ SAT pro: if you're better at applying math concepts to real-world scenarios
☆ ACT pro: if you're good at memorizing formulas
✔︎ The ACT tests a wider range of math concepts. 

The ACT has a bigger focus on geometry (30%-40% of ACT Math vs. less than 10% of SAT Math) and more questions on trigonometry. It also has some math concepts not on the SAT at all, like matrices and logarithms.

☆ SAT pro: if you're better at algebra and mathematical data analysis
☆ ACT pro: if you're better at geometry, trigonometry, and logarithms
✔︎ SAT Math accounts for ½ of your total score and ACT Math accounts for ¼ of your total score. 

This means that a lower math score on the SAT will significantly drop your total score more than it would on the ACT.

☆ SAT pro: if you excel in math, it will reflect in your total score!
☆ ACT pro: if you’re less confident in your math skills, your total score won’t be affected as much
✔︎ ACT Math gives you 5 possible answer options for multiple-choice and SAT gives you 4 options.

This means you have a 20% chance of guessing the correct answer for ACT Math versus a 25% chance of guessing the correct answers for SAT Math. And since neither test penalizes for incorrect answers, it’s better to guess than leave a question blank!

☆ SAT pro: better odds for guessing on math multiple-choice section
✔︎ ACT Math has only multiple-choice questions, SAT Math has “grid-in” questions where you write in your own answer.
☆ ACT pro: if you prefer multiple-choice questions
✔︎ SAT Reading has “evidence-support” questions. 

This is a big part of the SAT Reading section. These questions are connected to each other and build off previous answers, as well as cite lines directly in the text. 

☆ SAT pro: if you're good at reading questions where you have to find evidence in the text
✔︎ SAT Reading questions follow a chronological order, while ACT Reading questions are randomly ordered and are not connected with each other.
☆ SAT pro: SAT Reading questions may be easier to follow and answer more quickly because they are connected with each other
✔︎ The ACT has an optional essay, the SAT does not. 

The SAT used to have a mandatory essay section, which then changed to an optional essay like the ACT. However, as of Summer 2021, the SAT has gotten rid of the essay portion altogether.

☆ ACT plus: if you're good at essays and want to show off your writing skills!
