Is it at the same university?
Oops - I totally assumed it was, and I shouldn't have.
Repeating classes is another option - make sure you ask about the school's repeat policy before you get started, though. That's another area where schools vary GREATLY. Some will let you repeat whatever, others will only let you repeat classes where you got a D or F. Some will let you repeat as many classes as you want, others won't let you repeat more than a certain number of credits.
