Hello Shantanu,
I can understand your angst and anxiety. For doing any subsequent course even by distance education, query will be asked as to whether you are 12th pass or not. But do not worry. Many states have already granted equivalence to Diploma to 12th. Just ask administrative staff of your Polytechnic for the same and obtain it.

Yes, you can get admission in FMS as you have a good score.
Best of luck.
