Flik,
As I understand it, for someone in your position the short course would probably involve little more than familiarisation with the plane you will be flying (Katanas or Alpha 160s) and a few navexes to get accustomed to the local area and procedures. This might only take 5- 10 hours so you would get the rest (Full course is 67 hours) refunded back.
You only use the hours they feel you need.
