Yes, the more experienced you have with exams and studying, the better you get as your go through higher level of courses.
One thing I STRONGLY recommend you doing is spending about 2-3 hours studying per course each day. This studying SHOULD be aside from doing your homework. Homework should be done during a separate time, before the due date of course.
Take good notes during class, even if you are given the notes, take additional notes.
Read your notes 2-3 times everyday.
READ your book. Don't spent time playing games or being on FaceBook, spend your time in studying, because you will always have the weekend to do that, and these 4 years in your university are the MOST CRUCIAL time in your life, because doing well, meaning getting between 93-100, will get you a nice job or get you into a great graduate school.
