How do you prepare for exams?

Whenever we were having quarterly exams, I usually review my lessons a day or two before the examination. When we had our mock test and some Achievements test, I studied the given reviewer the day or three before the examination. I can review and memorize my lessons easily because I was given a high intelligence quotient. I could memorize a long poem in 30 minutes to one hour.

I'm also not a good learner but I always try to. I have a good strategy for study but i don't know whether it can works with another or not. I always try to collect as many as possible the previous exams paper and answer it completely in a book. When I've already finished on answering I'll buy a new book and try to answer it again (without writing them in full answer, just giving the key sentences). It is hard to remember all of the syllabus whereas only few of them will come to the exam. So, by collecting as many as possible of the previous exams and answer all of the questions, I can learn some of the material in the syllabus (but not all). I think this is enough for me to remember some portions in the syllabus rather than the whole because my memory is limited and if I force to remember all, I will forget another material which I've remembered. And try to study by involving more than one sense. Like you read loudly while you're reading.

Before when i was still an elementary student i always study at home every time. so preparing for exams is not a problem for me. But as i grow old I get lazy so all i just do before the exams is to read the book about the scope of the exams for 2 days.
