Taking 4 Classes Senior year

<p>I have 5 classes right now, 4 of which are important and the 5th was supposed to be an elective. I decided to take computer science but it turned out my schedule would not allow computer science so I am stuck with drawing, which I really hate. I know that it is probably not good to take 4 classes senior year but honestly would it make a difference if the only option for a 5th class is art? I have tried to see what other classes I could take but because of certain circumstances all that is available to me is art. In this position what should I do? Stick with art or drop the class so I can focus more on my other classes/other things?</p>

<p>I don't know if this is important but I am planning on applying to mainly UCs. I am just including that in case it makes a difference about the decision between 4 or 5 classes. Thanks.</p>
