When you take a test you are pretty much just showing your teacher or whoever, how much you have learned by demonstrating your ability to understand the things they have been teaching you. In order to help you on a test you have to be comfortable with the location of space, so that you are relaxed. Also, you obviously have to read the directions carefully because if not then how are you going to know what your test is about. Furthermore, when you have finished each problem, reread it just to make sure your answer is complete and somewhat right. In addition to, if you do not know the answer to a question, skip it and go back to that question later..
