CBSE 12th

Hello Vijay,
12th by NIOS is recognized by all and you would be definitely eligible provided you are fulfilling other criterias too if any.

Yes, Tushar, you are eligible. All the best.

Hello Sunil,
PG diploma indicates that it is "Post Graduate" diploma. Meaning you can do it only after obtaining graduation. Unfortunately two years if study for diploma or even obtaining this diploma is not equivalent to degree and hence unfortunately you are not eligible.

Dear Abhay if you are right now in 12th, than I personally believe that you must focus only on your studies. Don't go for numbers. Instead, try to keep your scorecard excellent. It is your scorecard that will keep you ahead of others. As far as admission is concerned, various colleges running such integrated course have their entrance exam. You can appear those in order to seek admission into such courses. I hope this would suffice. All the best and God bless you.
