At your orientation you meet with your advisor and pick your classes. If you have a choice I would pick the earliest session possible to have the chance to get the classes you want /need. You should though start reviewing your curriculum or at least classes now,so you can see what interests you. I would advise maybe calling Monday and speaking to an advisor just to give you a headstart on what you should be even looking at. You should know what classes transferred and which didn’t by now and that might give you a clue about what courses to take next. Just go online and pursue the curriculums.
