That is depends on you, in which college you want to get admission
so ‘’JOSAA’’-For NITs, IIITs(except IIIT-DELHI and IIIT-hyderabad) and some government funded technical institutes.
‘’JAC-DELHI’’-It includes only 4 institutes, these are-DELHI TECHNICAL UNIVERSITY(DTU), NETAJI SUBHASH UNIVERSITY OF TECHNOLOGY(NSUT), INDRAPRASTH INSTITUTE OF INFORMATION TECHNOLOGY(IIIT), AND IGDTU(FOR GIRLS ONLY).
and your jee mains score is also valid for IIIT HYDERABAD(visit official website of IIIT h for registration)
with JEE mains score, you can also get admission in IP university (DELHI)
I hope this answer is enough for you.
