Many students are curious as to whether they should take the ACT or the SAT. We will review the ACT vs SAT in this guide to help you learn about the similarities and differences. 

Both exams are used by colleges and universities across the country to help determine who should gain admission to their institutions. Each exam has various pros and cons that we will review below.

Summary: Review the ACT vs SAT and find out which exam you should take. If you will be taking the SAT, consider using a SAT prep course to help you get a top score.

ACT

The ACT consists of four sections: English, Mathematics, Reading, and Science. Each section is scored using a scale of 1-36, and the average of the four sections is the composite score.

The optional essay is not factored into the total score. Two readers score the essay using a scale of 1-6 based on four criteria: Ideas & Analysis, Development & Support, Organization, and Language Use & Conventions.

The sub-scores of each of the four areas are then summed to a final essay score between 2-12.

SAT

The SAT consists of two sections in terms of scoring: Evidence-Based Reading and Writing & Math; however, the exam contains three actual tests: Reading, Writing and Language, and Math. A total of 800 is provided for the scoring of each section.

The scores of those sections are added together to get your total score. 1600 is the best score you can get on the SAT.

The optional essay is not factored into the total score, and its score is shown separately in the final report. Essays are scored in each of three areas: Reading, Analysis, and Writing on a scale of 2-8. The sub-scores are averaged to produce a final score.

The ACT provides less time to answer each question. Both the SAT and the ACT test you on the same raw content in a similar manner, but the ACT gives you less time per problem to go through the same set of steps, and it bunches together the problems with fewer breaks. 

If you don’t work well under time pressure, the ACT may not be your best option. As you can see in the table above, students will have more time per question on the SAT vs ACT. 

ACT vs SAT Math

The ACT tests more advanced math concepts in trigonometry, imaginary numbers, advanced geometric shapes, and logarithms, but it accounts for less of the total score. The ACT has a big focus on geometry, which is about 35% of the ACT math questions.

Trigonometry makes up about 7% of the ACT math questions.

At first glance, if you are not strong in math, it would appear that you should take the SAT because it has easier math questions. However, math accounts for 50% of your final SAT score, whereas it only accounts for 25% of your total ACT score. Why?

The ACT averages the scores of all four sections to arrive at the final score. In contrast, the SAT adds the scores of the sections together to arrive at the total. Remember that both tests look at your score relative to those of everyone else taking that test, or your percentile rank.

If math is not your strength, you would likely have a better chance of getting a higher composite score taking the ACT. 

ACT vs SAT Essays

The ACT provides you with a topic and three perspectives on that topic. You must then write an essay in which you state your own perspective, developing it with reasons and examples. Your position can be related to or distinct from the ones that are provided.

The SAT gives you a wholly written essay and then asks you to evaluate that essay and find the evidence, the reasoning elements, and the structure.

If you are more of an analytical person, then the SAT essay will be easier for you. However, if you are more of a persuasive writer, the ACT essay will appeal to you.

The essay for the ACT is optional. As of June 2021, the CollegeBoard has gotten rid of the essay for the SAT.

ACT Science

The science section of the ACT primarily tests your ability to comprehend graphic information, though understanding some of the text of a passage is also required, particularly on the single Conflicting Viewpoints passage, which might contain no graphic information. A few questions will depend upon your knowledge of simple science facts.

While the SAT does not have a separate science section, scientific passages that test scientific concepts are sprinkled throughout the math and reading sections. The ACT science section score makes up 25% of your total ACT score, whereas the SAT has no separate score for science. If your goal is to get into a science-oriented program, taking the ACT may provide you an advantage.

Neither the SAT nor the ACT is more challenging than the other – but each test benefits a different type of student.  Since colleges accept both the ACT and SAT, you should take the test that best reflects your strengths.

Spend time getting familiar with both the ACT and SAT. Take our free practice testfor the ACT or SAT practice tests to get a better idea of some of the questions that may be asked on each test. Look at each section and get a sense of what types of questions and problems are presented, how the instructions are worded, and the general format. 

Keep in mind the amount of time you have to answer each question. For each question, you will need to be able to figure out what you are being asked and what information you are given.

In the process of making your decision, one strategy is to take an ACT prep course or SAT prep course.  Prep courses will help you figure out what you need to focus on the most and will help you get more comfortable with the exams. 

If one test appears to be more doable for you than the other, that is the one you should take. 

Once you have decided which test works best for you, you can use your efforts to study, practice, and time yourself for each section.
