Some people say that JSU stands for "Just Show Up," but this is only partly true. It is extrmely important to show up for all of your classes, but there is more required of you if you plan to be sucessful.
Reading is something you will be doing a lot of, as well as homework assignments. Although, unlike high school, most of the time professors won't even look at your homework. Do it anyway, though, because it will help you do well on your tests. Professors at JSU are friendly, and they will work with you if you are struggling in a class. Also, tutouring is available if you need it. Just talk to your academic adviser.
