My main concern is, should I let my mom claim me as a dependent?

Hi, I am 19 and currently enrolled in college full time. I need help preparing to file taxes this year! I want to maximize my return as much as possible, so should I claim dependent and able to be claimed by my mom? I worked during the summer and I also hold a work study position throughout the academic year. I live with another relative during the summer and on campus during the school year. How can I receive my max. return amount? How should I file?
