If you were 100% sure of a question and you get it right, then that's that.
If you guess correctly or if you get a question wrong, go over it. Look at each wrong answer and figure out what makes it wrong. Look at the right answer and figure out why it's right. Why did you choose the wrong answer? Why were you unsure of the right answer?
I would normally do a first and second pass through the notes but this was a VERY effective third pass. The questions you get correct are the bits of info that you have down pat but the ones you miss are the areas you need to brush up on. When you do all that stuff in the above paragraph, you are making sure that you remember everything else in the notes. I found that it 'sealed the deal' because you are applying it to something instead of just reading it. When I go to recall the info during a test, I find it easier to remember those things because I had gotten it wrong in a question once.
