Applying to Colleges for Fall 2015, but withdrawing from a class this semester

<p>So I am currently taking English 1A, Managerial Accounting, and Calc 3B. Im not doing well in Calc 3B so i was thinking of withdrawing and taking it in the spring semester. My question is whether this would affect anything such as my TAG with UCSB or any of the other UCs and colleges I am also applying to. This would be the first class that I'd withdraw from. Do I need to report this in my UC application. Any help/insight would be appreciated. </p>
