Questions will be based upon patent act and rules. To begin with read the patent office manual. You will find it on the indian patent office website. For patent drafting I suggest the following 3 books, but they will be extremely costly.
Invention Analysis and Claiming;
How to write patent application and
Landis on mechanics of patent claim drafting
You may refer to old question paper available on patent office site. I am not aware of any training institutes in Pune. However I recommend you to attend some of the 2 days or 5 days training program conducted by NIIPM, Nagpur. It is cheap and best compared to many training institutes.
Hope this helps. If you need any more info, pl let me know.
