Good luck Bro!
And remember to walk with a straight back, believe in yourself , if you believe that you're 7' tall, you might not become 7' tall, but you will appear taller to yourself and others, if you believe that you're the greatest man that walked earth, others will see you as a leader.
Don't be scared of crowds, new ppl etc... (I used to be) Get that fear over with first couple of days,(You don't want 4 yrs of it) don't walk a mile extra to avoid the new ppl and crowds, walk straight up to them, greet ppl, don't stop, just keep walking... (to avoid weird silence when nobody knows what to say)
Give your self confidence points - If you complete a task that you chose(can be as simple as greet someone, or stop and ask someone a question), give your self a certain amount of points, the harder task the more points. Your self esteem will grow as the points get higher, trust me.

But most importantly:
1. Be your self - with an overclocked self esteem.
2. Don't ever be a bully, that might boost your confidence, but in a false way, that will come back and haunt you later in life.
3. Make friends
4. Pay attention during classes(easier homework)
5. Make it a blast!

Ps. Advice from my wife: Always be kind, and remember what goes around, comes around.
