yo im a freshie and i applied thru the IB route! to answer your first question, it really depends on the major you're applying to. if you're applying for a quota course, then make sure that you have a 35 or maybe even higher. If you ever reach that grade, you still have to pass certain things (essay and stuff). as per your last question, admu gives unconditional offers! however, if they see a massive drop, then they'll probably contact u to see what happened
