Hi. I want to do dentistry but I'm aware that is it really competitive. Initially i want to do medicine but due to certain factors, i am more aligned to dentistry right now but just in case i might want to take medicine as my back up option. May i know would i be able to reapply to medicine if i got kicked out from dentistry. I intend to apply to different unis for medicine in that case. Would the unis know i've already applied to dentistry before ? Thanks
