Dear Aspirant,

If even after 7th round you did not get any college, this is probably because your rank is too low to get admission into an NIT or IIIT. In this case, I suggest you should either join some good private college or take a drop year and prepare again for JEE 2020. 

However, if your rank is slightly on the verge then you can look for spot rounds which will be held in the first two weeks of August. keep an eye on the college of your interest.

Hope this helps.
