Should I drop this class or not?

<p>Hey guys, so I'm a junior in high school and I'm trying to decide whether or not I should drop IB World for next semester. I think I can get an A-, but it's really shaky right now, and on top of that I already have two other classes that are in the same range (calc BC and AP Lang). If I dropped the class, I'd take normal world history instead next semester, and I'm not sure if that would look bad to colleges--if they would prefer that I stuck it through in IB World or they would look more at my grades, which would be higher in normal world history. Please help, and thank you! :)</p>
