I believe he conducts classes in most cities and in the city where the exam is to be held about 10 days before. Give him a call and see whether that's going to be the case this time. I had a friend who had gone to him for classes. He cleared it in his second shot. Flunked in II the first time.
I believe the 'SELCAL' questions have been done away with now. Expect 1-2 emergency/urgency questions. Question 5 (the one with multiple "sub-questions") is a little tricky, but don't spend too much time on that one. The pass % for part I is 50% IIRC.
The part that I found most ridiculous was the call signs:
Kingfisher = kingfish air
Jet Airways = Jet
IA = Ind Air
...silly.
