Despite all the SAT vs ACT pages, it remains one of the most FAQ. The short answer is if you like Superman better, go ACT. If you like Batman better, go SAT. Ok, I am (mostly) kidding. There is no short answer; you’ll need to do a little research. The table provides a quick overview. The text below it is for students who know the basic differences, but still feel unsure which will be better for them.

English, Reading, Math and Science Writing, Reading and Math
Essay is optional * Essay is mandatory
No penalty for wrong answers 1/4 point penalty for wrong answers
Higher level math but straighforward More conceptual math
Passage types are in predictable order Passage types are not in a set order
Slightly higher time pressure Slightly lower time pressure
Fewer, longer sections Several shorter sections
Colleges may focus on composite score Colleges may focus on area scores

* – ACT essay is optional, however some specific schools do require it. You should go HERE find out if the colleges you are applying to require it BEFORE you take the ACT.

ACT – If you are especially good at math and science, and specifically weak in reading and writing, you may want to go for the ACT – you can excel at 2 out of 4 instead of 1 in 3. The ACT essay topics are often easier to write about, and more latitude is given to the student in how to respond to the prompt.

SAT – If you are especially good at reading and writing, and specifically weak in math you may want to go for the SAT – you can excel at 2 out of 3 instead of 2 in 4. The SAT essay topics are a little dry, and there are stricter guidelines for responding to the prompt.

The best possible way to be sure, though, is to go ahead and try taking a practice test for each one. Many schools offer practice tests. If your school doesn’t, you can find an online or downloadable test, or buy The Real ACT Prep Guide and The Official SAT Study Guide both of which contain actual previous tests. If your ACT score is higher, or the two are about the same but your lower ACT area scores are in things you feel sure you can improve in, go for the ACT. If your SAT score is higher, or the two are about the same but you aren’t sure how much you can improve in the weaker areas, go for the SAT.

Common statements you’ve probably seen that I disagree with:

  • “The SAT has much more vocabulary.” This seems true on the surface, because the SAT has sentence completion questions. But the ACT requires a strong vocabulary to perform well on the Reading, and even on some of the English and Science.

  • “The ACT Math is harder.” This also seems true on the surface, because it does go up to a higher level of math. However, the ACT math questions are more straightforward – SAT math questions are much more conceptual. On the ACT, you may well hit problems you don’t know what to do with – and you’ll probably know that. On the SAT, you are far more likely to think you have correct answers only to realise later you forgot to consider some element of the problem.

  • “Everyone who is good at science should take the ACT instead of the SAT”. Again, seems true on the surface. I know I keep saying that, but so many misconceptions become popular precisely because they are believable on their face. ACT science is not about remembering and using all the detailed equations, terms and processes you learned in your science classes. It is about applying logical, scientific thinking. You won’t need to remember the atomic weight of Ag, or what Ag stands for. If you did well in forensics, psychology or sociology and have a good sense of what goes into a solid experimental design and how to read data, you can do VERY well on the science section even if you didn’t do great in biology, chemistry or physics.

   So why are Superman and Batman in here? Superman is very strong, honest and direct. He also runs around saving the world. So I associate him with the ACT – it tests to a higher level, in a straightforward way, and covers more area. Batman, however, well… World’s Greatest Detective. He patrols a smaller area, but more than makes up for not being superhuman by using his intellect to think things through and make them work to his advantage. If you want something you can punch through, go ACT. If you want something you can out-think, go SAT.
