Before a test, I assume the teacher let the student know before hand like a week or may be 2 days adance. I think the student should separete the work in different days, dont wait till the last minute. Do few the questions see if you know what you have a brief idea what the topic about. read over the notes that you took from the class and try to remeber the highlighted part. dont put too much pressure and relax, if you study 2hour every day before the test coming, you will do well on it.
