Are my subjects okay?

For some reason, I’m going to be inflicting self-harm upon myself by undertaking the IB diploma, something I am obliged to do at my school. Don’t get me wrong, I’m pretty excited to see PE and physics and the like come off my schedule, and I am pretty confident with my subject choices, but a little anonymous guidance would be very, very much appreciated, particularly because I’m aiming for schools that are quite selective, and I’ll need all the help I can get. My dream college has been thus far, and will continue to be, Columbia. In my freshmen year, I went through some emotional trauma and I spent several weeks in therapy and whatnot, so my grade for a large portion of the year were around B’s and in some cases C’s. This year my GPA has been quite high, and I’ve made it onto the honor roll, however my grades in math weren’t as stellar as I hoped they’d be.

Next year I plan on doing:

English HL
Math SL
Chemistry HL
Japanese B HL
History HL
Economics SL
(Religion, ToK, College Prep, etc.)

As for my extracurriculars:

Model United Nations
Track and Field
Speech
Debate
This program where we Skype call kids in southeastern Asia and teach them English.
Choir
One-Act Play
Social Justice Committee
Women’s Education Support Committee

Do you think I have a shot at Columbia?
