Mom wants to claim me.

I am 18 years old, and I am a full time college student living at home. My education is paid for in grants/scholarships. I worked at 3 different jobs this year and made over $3,300.00, while also attending 2 different colleges (Summer at one college Spring at another). My mom wants to claim me, but I am not sure how this will effect me. If my mom claims me does this effect my college? I wanted to do my taxes myself, but my mom says she can make more if she claims me. I have been told that if she does it could effect my college, and that I could make more money back if I claimed myself instead. Is this true?
