<p>I noticed that I need to take 2 subject tests (1 math level and 1 science) before applying to Cornell. I have taken math lv2 already but I still need to fulfill the science requirement. I haven't taken any of the AP science classes yet (I am taking all 3 this year) so I don't have a strong foundation in any of the subjects; I was wondering which one (Bio, Chem, Physics) is easiest to self-learn and score well on. Thanks!</p>
