How are my credentials for college?

You have ok credentials in order to apply to those colleges but its the fact that you have not taken any of the AP exams yet. You cannot expect 5's on all of the AP exams as they are difficult and I bid you good luck on them. As for your IB schedule, expect it to be difficult. I am currently an IB junior and I have an 8 cl schedule + various EC's + volunteering. If you are wondering, I currently take: IB English HL, TOK, IB Psychology SL, IB Physics HL, Honors Spanish 4, IB Chemistry HL, IB Biology HL, and IB Mathematics Sl. Keep your hopes high and good luck
