text: how do you prepare for an exam in 3 days knowing you'll probably flunk it???   first thing: believe in yourself!  if you think you'll flunk it, you probably will.  so then what's the point?  aim a little higher, like a d+ or even a c.  who knows, you could end up acing the thing.  second: get all of the notes.  if you've missed a lot of class, borrow a devoted student's and photocopy them all.  study those well.  third: to save some time, find out exactly what will be on the exam.  sometimes, the instructor doesn't put everything you've covered on it.  find out all you need to study for, get your required texts and some different colored highlighters and make a scavenger hunt out of it.    fourth: give your brain a brake.  don't study all night long and then try to take the exam.  get some sleep, take a warm bathe, watch a movie, go dancing, etc.  the important thing is to relax because when you're nervious, your adrenaline glands pump extra adrenaline through your body and block off the messages the dendrites in your brain try to pass each other.    fifth: find a study partner.  chances are, you've missed something, either by spacing out or just because our brains don't work like tape recorders.  find the biggest brain with the biggest heart in your class and be extra grateful when you find you've passed your exam.   good luck to you.  hope this helps.
