Many research implies that enough sleep time make the brain works well. Because of this, I try to fall asleep early the day before taking an important exam.
Second, having trouble with digestion during the test can make me hard to concentrate completely on tests. Because of this, I try to have light breakfast which consituted with food which can be easily digested.
Third, I try to summarize all of the range for the exam. There would be the summary which I made already, but summarizing those thing one more time helps me recall the contents during taking exams.
