B.Des

What do you mean by proper UG degree?

Yes, both GDPD from NID and B.Des from NIFT are equivalent and both the colleges are two best colleges for design in India.

B.Des is a better course than GDPA.

You should know the basics of drawing at least, rest the details are taught during the course only. IIT is one of the best institutes to do B.Des course because of its recognition.
But, you can apply for these colleges as well:
1. NID - Ahmedabad
2. Symbiosis Institute of Design – Pune.
3. UPES – Dehradun.

Yes, it is a good option to pursue designing courses. You can also opt for MIT or Symbiosis.

No. In order to pursue B.Des, you need to appear for the entrance exam of NIFT after completing class 12th.
