Dear Aspirant,

If you're interested in research field like mathematics and/or physics, then you can join Physics Hons. In Delhi University. It is a three year course with a very good reputation and you will find it very helpful and interesting if you're into physics and maths. Moreover, you can also give JEE examination after your 12 for admission not only in engineering courses but also for admission in science courses like BSc provided by few IITs.

Hope this helps. Thank you
