Congratulations! I'm a transfer student, and I will be attending CSU next semester. It's a great school.
If finances will be a factor in deciding which college is best for you, I would highly recommend filling out scholarship and/or financial aid apps as soon as possible. For some freshman scholarships, you will be considered for automatically if you meet their requirements. Take a look at the website and call the admissions office or the office of student financial services if you have any questions. I'm sure they'd be happy to help.
Here is a link to a website that may be of some help if you haven't gone over it already. Scroll to the bottom for phone numbers and addresses of the offices I just mentioned!
