How long you studied in a day ?

when i was still in school, i used to allot 5 to 6 hours for studying, especially during third year and fourth year college. This is not continuous, though. I have breaks in between. Reading in advance before coming to class is a very effective way so that when exams are near, you don't need to thoroughly review your materials cause you already know them. Cramming is also not advisable. For sure, there will some items in what you've study that you will fail to remember during exams. =)
