<p>Well i believe that 5 hours for one test is absurd… It depends on the test and on the class, but for a difficult test, I use to study a max of 2 hours. The class that is most difficult for me is science, in that test I study about 2 hours or less and I get a high grade, but studying for one single test 5 hours, i will never handle it, I am not capable of staying in my room for 5 hours!! it is crazy. For the rest of the classes like math, spanish or english i ussually study about one hour or less depending on the topic of the exam.</p>
