Notes/ questions for tech specific exam

[xeopskzu]

I am likely to acquire an Indian CPL(H) in a few months. People have advised me to appear for tech specific exams on single engine helicopters held by Indian operators. Can anyone give me some study material for these helicopters and also confirm which all can one appear for without having to show proof of having undergone the technical training? I recently appeared for and passed the exam for Bell 407 as I had some notes.

Things may be different in India but in the EU you have to do an approved (by the relevant civil aviation authority) course at an approved training organisation (ATO).
I haven't double-checked but I don't think that PPRuNe is an ATO.:rolleyes:
