Architecture

You stand a good chance. You will most probably get the seat. All the best for your future.

Yes, you can take admission in design college on the basis of JEE Mains paper 2. Since NATA paper has a huge weightage of drawing, abstract and aesthetic sensibility, it is given more importance than any other exams. On the other hand JEE has been producing brilliant architects for as long as 40 years now. Both the exams have an equal importance in the field of design. You can either appear for one of them or both. Appearing for both, however, will give you the upper hand.
