JoSAA

Yes you have chance to get into some IITs but you will not get top branches. You will get least ranked branches. Check in predictors provided in Shiksha to get approximate idea.I have listed some colleges and branches you are eligible . But you need to check the gender based reservation also. You will not get home State quota reservations in IITs so no need to check that.

Kindly do some research and join accordingly . If you are searching seat for gender neutral then I am sorry you won't get any seat in IIT.

You cannot get admission in CSE in any of the NITs or IIITs ,but it's also based on your category. For open category there are no chances to get into NITs or IIITs. If you are SC or ST category you may get a seat.
Especially by Josaa you will surely not get a seat , sometimes you may get a seat through CSAB special rounds .
You may get seat in least branches.But if you are Home State student of particular NITs or IIITs or GFTIs you may get a seat .
You will surely not get any seat in Josaa rounds . So you need to opt for CSAB special rounds so that you may get seat in some NITs or IIITs or GFTIs for some branches . CSE is not a sure thing but sometimes you will get due to luck. It depends on the number of persons who have more rank than you appearing in CSAB rounds and number of seats left in those colleges in those particular branches .You'll have 3 options now:
Settle for some other engineering college and go ahead with its curriculum.
Settle for some other college and work for both your sem and next JEE prepration.
Join in some long term institutes and prepare well this time and give next JEE.
