Should I take the SAT or the ACT?
According ACT, the main difference between the two tests is that the SAT measures aptitude whereas the ACT measures high school achievement. This, however, only really applies to the math section. You do need a bit more knowledge in math to succeed on the ACT. But it's not necessarily true for the other parts. The writing and English sections are very similar in both tests (especially since the SAT is now changing), and the science section does not require much scientific knowledge (it is more about reading and interpreting graphs and charts).
One major difference is how the questions are presented. The SAT questions, although slightly easier than ACT questions, can be presented in a tricky way. Conversely, ACT questions, although they can be harder than SAT questions, are very straightforward.
Another MAJOR difference between the two tests is very obvious if you sit for a practice of each. You have to fly through the ACT to get it done. You cannot sit and linger over questions. Learning to be strategic with your time is essential to being successful on the ACT.
