ACT vs. SAT  

When your high school years are coming to a close, and you’re ready to hit the ground running, you may have to push through one more task before applying to college: making the decision of taking the ACT vs. SAT. 

The ACT and SAT can be daunting, particularly if you don’t feel as though you have the knowledge or tools to prepare. That’s why it’s useful to look at a full rundown of both tests, understanding their similarities and differences. 

While some students may have the means and privilege to take both standardized tests, this isn’t an option for others due to the costs. And it can be overwhelming to buckle down and commit to one or the other if you don’t really know the difference between the tests.

Although the differences between the ACT and SAT upon first look may seem minor, some of them may significantly affect your decision. To decide which test (if either) you want to take and send to colleges, it can be incredibly beneficial to look at all the differences between the two. Considering each key difference regarding the ACT vs. SAT is a great way to start your plunge into standardized testing. 

ACT vs. SAT Rundown 


A key way in which these two tests differ from one another is their structures. 

While the SAT has three sections, the ACT has four. The SAT has a reading section, a writing & language section, and a math section; the ACT features reading, English, math, and science reasoning. 

Additionally, as of last year, only the ACT will offer an optional essay component. If quickly  analyzing and responding to a passage is a strong suit for you, then this might be your golden opportunity to shine. Or, this may be a breath of fresh air if you cringe at the thought of pumping out a coherent response after sitting through the entire test. 


Time allotted per question can be a game-changer if you either excel or crumble under pressure. If the latter applies to you, you might prefer the SAT, since you’ll have more time in each section to answer the questions. 

In each section, the SAT offers more time per question. The following table by PrepScholar illustrates these differences:

Reading 53 sec/question 75 sec/question
ACT English/SAT Writing 36 sec/question 48 sec/question
Math 60 sec/question  

No Calculator: 75 sec/question

Calculator: 87 sec/question

Science 53 sec/question N/A


All in all, if you include the essay portion on the ACT, the SAT is the shorter test. If you know you won’t be doing the essay question, you can take this factor out of the equation. 

ACT vs. SAT Score Range

Another difference between the two tests is their score ranges. Below is a chart that shows the ACT vs. SAT scoring ranges, which you can use to convert one to the other. 

While the different score ranges don’t really affect which test you’re going to take, this type of chart is helpful to have once you’ve taken one of the tests. Even if you’re not planning to take both, you can look at how your ACT score might convert to an SAT score, which can be helpful when you’re trying to figure out how your scores stand for a certain school.

Science Section

One major difference, which may be a tipping-point for many students, is that the ACT includes a science section, while the SAT does not. 

However, it’s important to note that the science section on the ACT doesn’t truly test students’ science knowledge/skills, but instead, their reading comprehension ability. In that way, it’s extremely similar to the reading section.

So if you excel at answering questions based on passages (that you’ll read in a short period of time), the ACT may be for you. 

Math Sections

If you’re looking for something devoid of math, you’re unfortunately out of luck. While both the ACT and SAT have math sections, there are some differences that may influence your decision when choosing which test to take.

One key difference here is that the SAT has two math sections: one on which you’re allowed a calculator, and one where you solely have your brain. (This isn’t to say that it’s more heavy on math—both tests have a very similar amount of math!) 

The type of questions you’ll face are also somewhat different. On one hand, the ACT features math questions that are usually pretty straightforward and not intending to test you on reading comprehension, but the math concept. 

The SAT, on the other hand, is big on giving questions that involve some reading comprehension and data analysis. 

In essence, the ACT is a bit more straightforward, while the SAT takes a little more thinking outside of the box. For instance, the ACT often features slightly more questions on broad topics such as geometry and trigonometry, while the SAT tends to highlight word problems, testing your skills of applying your knowledge to a real-life situation. 


The one considerable difference between the reading sections on the ACT vs. SAT is that the ACT reading questions generally require you to read or at least skim the entire passage. On the contrary, for the SAT reading section, you can usually succeed simply by reading the questions and finding the answers in the passage. 

The ACT reading questions don’t follow any type of order, while the SAT reading questions are usually chronologically arranged regarding what occurs in the passage. 

If you excel at quickly remembering small details from a passage, you may find that the ACT is the test for you. If reading a lot of text in a short period of time and then answering randomly ordered questions isn’t for you, the SAT might be a better choice.  

ACT vs. SAT: Still Don’t Know Which to Take?

Don’t worry—you’re certainly not alone in this struggle. Students (myself included) often take their time to figure out which test is best for them. If you have the option, it’s very helpful to take diagnostic tests for both the ACT and SAT. 

This type of practice test can help you figure out where your strengths and weaknesses lie, and if one test seems more up your alley than the other. 

You can also seek external help. Maybe your parents or siblings have experienced this process, and can provide you with some insight. Don’t forget about your friends! They’re going through this too—and although discussing standardized tests may feel a little awkward, chances are, they’ll appreciate the chance to voice their concerns and challenges with someone going through the same thing. 

Of course, many students will seek support from their teachers, advisors, or tutors. Some students are going back to remote work, so this may be a challenge. If you don’t have resources at school that can offer you the support you need, consider looking at online resources. 

Online tutors, such as those at My Private Professor, can provide you with helpful practice, advice, and suggestions for choosing a standardized test.
