#1: Time Per Question
the time crunches? Then you might prefer the SAT over the ACT. This is because the SAT gives you more time per question than the ACT does. So if you’re worried about time management, particularly on math questions, the SAT offers much more workable and far less stress-inducing time constraints than the ACT does.
While the ACT contains a section entirely devoted to science, the SAT does not. Science constitutes one-fourth of your total ACT score. So if you’re a science whiz who loves the idea of having an entire section focused on scientific data, graphs, and hypotheses, the ACT might be a better fit for you.
#4: Types and Balance of Math Concepts
In regard to math content, the ACT and SAT both have a big emphasis on algebra, but the ACT also tests Geometry. The ACT also tests a few concepts that the SAT doesn’t test at all. These include things such as matrices, graphs of trig functions, and logarithms. So what does all this mean for you? If you’re good at algebra and data analysis, you’ll likely do well on the SAT. But if you’re a fan of trig functions and geometry and are comfortable with matrices and logs, the ACT is a better choice.
#6: Importance of Math in Final Score
How big of a role will Math play in your final score? The answer to this question depends on whether you're taking the ACT or SAT. On the ACT, Math accounts for one-fourth of your total score (your Math section score is averaged with your other three section scores). On the SAT, however, Math accounts for half of your total score, making it twice as important on the SAT!
So if math isn’t your strong suit, consider opting for the ACT. With the ACT, a lower Math score won’t negatively affect your total score as much as it will on the SAT.
In other words, if math isn't one of your strengths, you’ll have a better shot at hitting the total percentile you want on the ACT than you will on the SAT.
