You are eligible again in 12 months...I understand time line might be shortened to 6 months. It only hurts your chances in that it sets you back that period of time. If you fail a second time, they will not process your application any further. I know quite a few guys who have passed on the second attempt.

I don't think you can really prepare for it. If you answered truthfully, you are doing it correctly.

Good luck next time round.
