I just took the pre-SAT. I thought it was going to be harder than it actually was. When I took it, it took 3 hours. The first part was reading passages and answer questions about it. That was 1 hour. The next part is on grammar. You look at sentences and figure out if they used the right set of words or punctuation. That was 45 min. The 3rd and 4th part was on math. On the third part there was like 12 multiple choice questions and like 4 problems you had to work out. The fourth part had like 21 multiple questions. and 4 problems you had to work out.
