What Uni + college courses do you want to study (I would list them 1-6 Most important to least important)
Personally I would drop Geography (seems useless) and History, they would be dead meat to me, really useless.
Plus it will give you more time (of the little time) you get to study and revise for the subjects.
I will tell you though triple science is the most important and most enjoyable I had so much fun, but it was towards the end of year 11 knowing it would be over.
