I think the exams in high school are by far way easier than college exams. In high school the teacher almost always gives a review sheet before the test. Studying is then easier because you know what exactly to study for. In college, however, the professor does not give review sheets before the test. You have to look over all of your notes and be familiar with just about everything written down because there's a possibility that any of the material in your notes could be on the test. Another difference is that tests are given more frequently in high school. In college, tests are given once a month or once every other month. So if you do bad on an exam in college, there's not much to help that grade out like in high school. For example, you could do bad on one test in high school, but make all 100's on your other tests and the bad grade then does not hurt you as bad. College tests forces you to be on top of your work and notes. It also forces you to be more responsible because you payed a lot of money and you want to make good grades for the money you had to pay. For these reasons, college exams are harder than high school exams.
