if you are medically declined (what ever the terminology is) and are accepted - the academy will automatically request a waiver on your behalf (i am assuming this is unless it is something that permanently prevents you from performing your duties) - you will submit any supporting documentation if needed and a determination will be made - if you are granted the waiver you go forward - if you are not then you will have the option to appeal at which point you can appeal and you can submit further supporting documentation - if approved - you continue on - if not you may be offered a deferral to the next years class - which has an entirely other set of requirements
