will I get money back if I drop out of college?
It is common that universities will refund a almost all of the tuition you have paid if you withdraw from the university within the first week. It is often gradated after that, with a smaller percentage of tuition and fees being returned the later you wait to withdraw. 

If you attend Colorado State University (CSU?), then it looks like you can still get 75% of your money back. They give you until September 2 to withdraw and get 75% back. The first day of school was the deadline to get 100% tuition back. You would need to talk with the registrar's office directly about all of this though.
