Since ACT has been becoming more popular in the last decade, SAT has been trying to copy ACT more. The tests are becoming more and more alike. SAT is even trying to hire away the ACT question writers. If you prepared for one, you should take both just to pick the one where you're at higher percentile. ACT has science, an additional topic. However, it is more reading comprehension and logic. You don't necessarily have to take all the science classes to do well in it.
