NIT

I think 33000 is your category rank if it is true than your CRL must be around 1 Lacs then you have the chances to get the NIT and iiit for this you have to visit the official website of CSAB to find the previous year opening and closing rank for NIT and iiit. If 33000 is your CRL then you have a excellent chances to get into top NIT top branch for that you have to visit the same website. And also if this is your first attempt of JEE Mains then I would suggest that you have to take a one year drop and prepare well for next year with full dedication and patience and consistency you will definitely get higher ranks in JEE Mains and may be you will qualify JEE advance exam next year, so think wisely. 

The cost to study a 4 years integrated M.Sc programme in NITs differs. As an example, at NIT Patna, the total tuition fee of a 5-year Integrated M.Sc. (Physics/Mathematics) amounts to about 6.25 Lakhs Rupee with a total fee including hostel, one time fees etc. coming around to about 7.52 Lakhs Rupee. On the same note, NIT Rourkela shows its aggregate academic fee of approximately 1.93 Lakhs on its 5-year integrated B.Sc. + M.Sc. courses in 2025-26, and 4.68 Lakhs in 2023-24. Such charges tend not to cover hostel and mess charges, which may really increase the overall cost. The precise costs are subject to the certain NIT and the specialisation selected.

With a 93.36 percentile in JEE Mains and belonging to the General EWS category with a Rajasthan home state, you have a good chance of getting into several NITs and IIITs. While you might not get into the top-tier NITs or IIITs for core branches like CSE, you can likely secure a seat in other branches or in lower-ranked NITs/IIITs. 

NITs:

Possible NITs:

You have a good chance at NITs like NIT Agartala, NIT Meghalaya, NIT Raipur, NIT Jalandhar, and NIT Goa.

Potential Branches:

You could potentially get into branches like Civil, Chemical, Electrical, or Mechanical Engineering in some of these NITs, or even Computer Science in lower-ranked ones. 

IIITs:

IIITs to Consider:

IIITs like IIIT Pune, IIIT Lucknow, and IIIT Gwalior might be within reach. 

The next five years hold a strong future of Aerospace Engineering; rising air traffic, need of sustainable aviation (e.g. electric/hybrid propulsion, biofuels), growth of autonomous flight systems (drones, AI) and continued space missions. The result is constant demand of engineers in design, testing, manufacturing and maintenance in areas of commercial, defense, and space. In addition to IITs and NITs, good colleges to study Aerospace Engineering are Indian Institute of Space Science and Technology (IIST) Thiruvananthapuram (directly associated with ISRO), Manipal Institute of Technology (MIT) Manipal, SRM Institute of Science and Technology Chennai, Hindustan Institute of Technology & Science (HITS) Chennai and PEC (Punjab Engineering College) Chandigarg.
