Hi Gaurav,
I will suggest, you should opt for a Master's degree for future prospects but it depends on you. If you are looking for a professional degree, you can go for a PG Diploma. Masters is useful for a research oriented career.

MBA has wider scope and opportunities as MBA graduates can be employed in all types of industries and all management functions. Whereas, PG Diploma in banking and finance graduates can only be employed in BFSI industry. If you want to work in BSFI industry only then PG Diploma in banking and finance is a good option else you may prefer MBA.

Nowadays it is not a problem to get the notes. You can get everything on the internet. You can get your notes on the link mentioned below: www.scribd.com
All the best.
