If your school allows retaking of courses and then only applies the higher grade, then that is great.Try not to overwhelm your schedule by taking too many classes. Se how you fare with a basic full time course load (12 credits typically). Also, consider whether or not you would prefer any of those courses to be online. I personally have only taken one course online which was one credit. I didn't like that format, but many of my fellow students take at least one course online per semester. In the Nursing program at our institution, there aren't any online courses-just the pre-req's.
