I just had the PSAT today and I though it was a waste of my time. I am in an american school, but I will not be going to go and study in the US, so I don't need it. I didn't mind the fact that I had one day in school, but with out classes.

Still, taking a 6 hour test isn't my idea of fun. When I took it last, I had to do the new writing section, which was hard because the prompt was stupid.

This topic is about two years old, I posted in it because I have taken the horror that is the SAT a few times. And at my school you have to take the PSAT. I think the questions are about equal in difficulty, but the PSAT is shorter, so it is easier.
Then the ACT is easier than the SAT because it has other subjects like science, and you aren't penalized for wrong answers.

i take the ACT next week

Well, if you run out of time, remember that you can guess and not be penalized.
