Reviewing Sample Exams

Hi All, I haven’t started any practice exams or questions yet (planning to start in about 2 weeks when I have gone through all the material), but was just wondering once you actually take an online CFA/Schweser exam can you go back and do the questions again or review the answers at your own leisure, i.e. do we ever see the questions again?

Guys, if you say you go through all materials or you done FSA or anything else do you mean you have appropriate knowledge on that part or you just finished reading or something similar?
