Do your best to be realistic with your course schedule and don't take more than you can handle. Stick to 12hrs your first semester because you don't know what you can handle yet! You won't always have a lot of options for course times, but when you do give yourself some days with later classes and make life easier. Barring a lunch, try to avoid huge gaps between classes if you can. Finally, if all of your class are on say Tuesdays and Thursdays reserve Mondays and Wednesdays for school work because all of your assignments will be due the following day.
