Yes, i failed once and i went again and again. You have to be really thick skin to keep calling them and ask for reschedule. Alot of people think that you can only try once but the fact is you can keep trying. The compass test you take is vaild for 3 years. I called them until they know its me the moment they hear my voice. I did about 7 interview before i was accepted.
My education is really not that good but its the passion you show them that you really want to become a pilot and i think that make them accept me.
