I would think (I am not a dermatologist) that acne, as long as it does not interfere with wearing any type of clothing, or carrying loads, or proper grooming, should be waiver eligible. If you had an LOA you would be in better shape than not having the LOA because they would holding a spot for you. That being said, almost everyone on here "waiting" is in the same boat as you, waiver or no waiver needed. Admissions is working to clear waivers, fix CFA problems, and make determinations as to whether WP or USMAPS is appropriate. Try not to stress, it will only make the wait more difficult and stress your parents along with you. Just remember, you are pretty much in the same boat as I don't know maybe 600 other people who will get that BFE. Keep your Plan B working (just in case) and don't stress out, there will be plenty of time for that after you get appointed. GOOD LUCK!!!
