<p>Excel in your SAT II subject tests? </p>
<p>If you really want the validation, you could take extra SAT IIs or prove it through AP or IB tests… Just realize that they will only be able to see the tests you take in Junior year, so you’ll have to plan it out so that you can show some pretty decent test scores to the colleges. Also, while IB doesn’t let you take the exam without enrolling in the course, AP does. So, if you’re taking an IB HL course (which you won’t test for until your senior year) you could take the AP test in your Junior year if you prepared enough and that could lend some credence to your academic talent.</p>
