She's currently a Sophomore who's planning on rushing
next year. She has this quarter (Fall), as well as Winter, and Spring to pull her grades up. Any classes she takes during the summer, either at UCSD or transerfable credits from a community college, will also pull her grades up. As long as she stays focused on her studies she should be able to improve the GPA.
OP~ make sure you seek out what ever resources you need. OASIS
http://oasis.ucsd.edu/ and your college's Academic Advisors are two places you should defintely go for help. Having "been there, done that", I bow down to the Academic Advisors because they're totally the reason I was able to graduate.
