Hi,
Kindly check this link of college website for details and facilities provided by the college:

Why to go for B.Sc then? Just do the graduate and PG course in interior considering the latter part and it's done! Interior design'n is more about how much practically you have been into it and less about the degrees in your resume! There are people who are doing laurels just after taking the graduation course.

NIT does not allow admissions through Diploma.

Dear
According to me, you should plan for B.arch and do job to understand the job market in both the profile whether in Architecture or Interior design then you may consider option whether it's M.arch or MBA according to your interest and career goal.
All the best.

The course of architecture batch involves math and NEET has biology. So, it will be very difficult and tens to impossible.
