SABIS publishes the college admissions right on it’s website, so if no one at your own high school is doing the counseling, get help from one of the other branches. If you still want outside help after that, contact the advisors at the AMIDEAST office closest to where you live.
Are the AP exams formally part of your program? You don’t need any AP exams if you have IGCSE results. AP scores aren’t used for college admission. They are used for credit or advanced placement after you have enrolled. Many colleges/universities will award credit or advanced placement for your A Level results. So you can save yourself some time, trouble, and money, and skip the AP exams. You have a lot of exams listed as self-study, drop those and focus on the exams that are directly related to your classes. From the looks of things, you already have plenty of those.
