You can put this solution on YOUR website! um what do you mean? like studying with 30 minutes left before you crash? or cramming before a test?
well if you don't have a lot of time to study on individual days, like me, you should try spreading out your studying so you can study 30 min. mon. tues. wed. and thurs. (a total or 2 hrs.) and then when you have a test friday that you will probably ace.
but if your cramming, not that i suggest it, but it's always good to review as many time as possible. so several quick skims of the material should do the trick, or at least to pass.
