Hi Krisakira. Congratulations on going back to school next month! Did your school give you a list of books for your assigned classes? If so you can check out Chegg, Half and other sites to see if you can get your books cheaper through them. Chegg is great and I highly recommend using them if renting textbooks is something you are open to.

Make sure you take a bunch of snacks with you on days when you have several classes in a row. 15 minutes usually isn't enough time to stop and grab a snack at a campus cafe. I would also take a bottle of water or something with you.

I am not familiar with your school but the beginning of the semester is always hectic and parking is usually VERY hard to find! You should probably time how long it would take you to walk to each of your classes across campus to make sure you can make it w/in 15 minutes. I know at my school I would never be able to walk back to the parking garage and move my car to another parking deck on campus in 15 minutes so I just walk.

Also, you can try to cut through buildings to get out of the heat.
