SAT Vs ACT: Key Differences in Detail

Time Allotted to Each Question

The SAT Does Not Have a Science Section

If you think that Science is not your strong suit, then you must take the SAT as it does not include a Science section like the ACT. However, the SAT may test your scientific knowledge under any of its sections in the form of passages, data, or charts.

The ACT, on the other hand, has a Science section that you would be required to complete in 35 minutes. In addition, the weightage of the Science section would also be equal to that of its reading section. 

The Math Section

The major point of contradiction between the two tests is that the SAT Math section is divided into two portions: Math Test–Calculator and Math Test–No Calculator, unlike the ACT Math section. 

The SAT tests your problem-solving skills in all sorts of situations revolving around your college math, science, and social science courses, the jobs you do and your personal life. To the contrary, the math section in the ACT is aimed at testing the mathematical skills that you have gathered up to the beginning of the 12th standard.

Frequency of Test

Difficulty Level

The difficulty levels of both tests are somewhat similar. That being said, it would significantly depend on what your weaknesses and strengths are. For instance, if you are confident that you can score well in Science, then the ACT is certainly the right fit for you. 

Again, as mentioned earlier, the SAT gives you more time for each question under each section. 

Essay Content

In the SAT, the writing assignment will ask you to analyse a text and explain how the writer makes an argument to persuade an audience. The same shall be supported by evidence from the given passage and completed within 50 minutes. 

The ACT writing test will be 40 minutes long consisting of one prompt. What you would be asked to do here is read the prompt and write an essay explaining your own stand on the given issue. It will be scored on the basis of the perspective you build and express in the essay. 


The duration of the SAT is longer than the ACT, at three hours and 50 minutes with the essay and three hours without the essay. On the other hand, the ACT is three hours and 35 minutes long with the writing section, and two hours and 55 minutes without the essay. Given below is the section-wise distribution of time: 



English: 45 mins

Math: 60 mins

Reading: 35 mins

Science: 35 mins

Writing (optional): 40 mins

Reading: 65 mins

Writing and Language: 35 mins

Math Calculator: 55 minutes

Math No Calculator: 25 minutes

Essay (optional): 50 mins

Which is the Right Test for You?

What is important to understand is that no institution would favour the scores of ACT over that of SAT or vice versa. The purpose of both the tests is the same, which is to check the readiness for admission to colleges/universities. 

The syllabus of the tests would have a different impression on each student. The best way to learn which exam would be ideal for you and your abilities is by taking practise tests of both the  SAT and ACT.

Should I take the Optional Essay?

The optional essay included in both the SAT and ACT does have an impact on your admissions. A great number of higher education institutions across the world choose to review individual essays to select students or make course placement decisions.

Nevertheless, many universities do not require the scores of optional essays and hence it has been made optional by administrators of both the tests. 

Note:  SAT Subject Tests and Essay is Discarded officially by College Board

Should I Take Both SAT and ACT?

Taking both the tests comes with a number of advantages. Find out what the advantages are:

  • Submitting scores of both the tests gives universities more information about you. 

  • You can make an informed decision while sending your scores to colleges and choosing the one that shows your strengths more.

  • Many US colleges or universities offer scholarships on the basis of scores of both ACT and SAT.

  • Some institutions accept scores of both the tests, which allows you more flexibility in case you score low in one of the subject tests.

  • Taking both the tests definitely makes way for more options and eventually decide on which university to say ‘Yes’ to.
