i know how you feel. i was nervous too before school started. why not call some of your friends and find out if they have the same schedule as you? maybe ask one of them to meet you there in the morning and you guys can walk your schedule and get familiar with it. as for not knowing people, you never no. a lot of times its really a surprise on the first day because you never no who will show up in your classes. i hope this helps and gives you some ideas! good luck!
