You have four tutions in a day ive not get time for study so should you study very late night?

Well the simple answer is yes, but you should always start studying very early in advance so that way you can avoid studying late at night. But if you dont have time then you its up to you, stay up late, be tired for the exam, and get a good grade OR study a little that day, be perky for the exam, but not do great on it
