So why dont u read that Training Document that DGCA released which clearly states the requirements for A320 - B737, ATR etc.
Just go by the syllabus written there and i am sure you would not be given any problem by the DGCA. That is the same information that would have been on your NOC.
Check the CAR's - Section 7 - Part 19
The second thing is making sure the TRTO syllabus is approved by DGCA. That you could confirm with the TRTO you are going to, if they have submitted the requisite syllabus etc.
By the way, how much have they quoted you for the TYPE?
Last i remember HPA was charging $21,500 for the DGCA specific type.
Good Luck
