should i drop out of this class?

im taking cis2010 rn & im not sure if ill get an A which is what i want since im transferring to UGA & plan to apply to law school (for which u need a high gpa). how bad is it to have a W on ur transcript? im going to have to take cis2010 bc its a major class but i can just take it at uga when i transfer. any thoughts??
