Strategy for practicing exam kit

I only have enough time to practice the exam kit once (I'm starting today). Is there a certain way I should practice it meaning I could note one question for each topic and then practice those questions before the exam or should I make notes for each question in the kit so that I know what I'm doing wrong for each question. The first method is much faster but not sure if it is effective. The second method takes a lot of time and I'll have to revise those notes again before the exam which along with the OpenTuition notes will be a lot to go through. I am quite in a panicky situation as I don't have a lot of time and not sure what to do to make the best use of my time.
