USC Transfer Advice

<p>So i'm a biology major currently attending a CC. I want to transfer to USC in Fall 2012 with a sophomore standing... But I'm taking a calculus class and i'm not doing so well. I have a C so i'm deciding whether or not I should drop it and get a W. What would you recommend? Should i just take the C and hope for the best or get the W and try again later?</p>
