hi, thanks for your reply! I contact the campus and they told me that I need to take cal courses in college, they can not accept ap score in econ major. Now I am taking both cal 1 and cal 2 courses. What I wonder is whether taking the course right now is considered late for application? Because I will finish my courses and report my grade at the mid of the march. I don’t know whether we should finish all pre-required courses before they begin to review the application. Thanks!
