Since I'm a CBSE student, I haven't really taken any AP classes and taking them here is kinda expensive. It is absolutely necessary to take AP classes and if yes, are 2 AP classes enough? Also, As an international applicant, are my ECs and academics good enough? Any suggestions are much appreciated!
