Handle Straight

how to handle 8 hours of class straight?

This semester I will have 4 classes in one day back to back which results in 8 hours of class straight. I do not know how to handle it- I am afraid that by the last two classes I wont be able to pay attention.
Any suggestions to keep my alert, awake and rejuvinated for each class? I only get a 10 minute break in between which consists of walking across campus to the next class.
Please help, I do not want to do poorly in these classes just because of my schedule!

Make sure you eat snacks and have fluids during this time. Maybe try and call a friend during your walk to give you a sense of social awareness during your day.
