senior year course load

<p>Hi everyone--
I am an IB diploma candidate and just started my senior year, but I am considering dropping my higher level Spanish 5 class because I do not need to take it to get my diploma. So if I did drop that, here would be my new schedule:
IB Biology HL- yearlong
IB Math SL -yearlong
Guitar (for my required art)-yearlong
IB English HL-yearlong
IB History HL-yearlong
Economics-semester
If I want to be admitted to UCLA, UC Berkeley, and USC, does this schedule make me competitive in terms of a strong senior courseload or should I keep the Spanish?</p>
