Wait Lists are rejections - that’s the reality. The schools didn’t accept you.
You haven’t been out right rejected…yet. You will only be offered a spot IF these schools take enough students off the waitlist…and you are included.
Were you already accepted anywhere? If so, I would suggest you look at those options.
ETA…as an international student, these are all reach schools. Did you apply to any sure things for admission.
And one more thing…where would you think you would apply to medical school? Medical schools here accept a VERY small number of international students and most are from Canada. And for both business and medicine…what was your plan for after graduation?
