I heard that a lot of US students take both the ACT and SAT Reasoning Test. Do people in NZ do that too? Would you recommend it?
ACT and SAT are different in terms of format and content. Some people tend to perform better on one than the other. They are viewed equally by U.S. universities. Your time is limited so it would be a good idea to try a practice test from both and see what you are more comfortable with before committing to studying for one.
