hlwo aspirant

hope you are doing well

You have to score above 94 percentile to get iiit and that too u will get ece branch or other lower branches in some iiits With 88 percentile, you have a good chance to appear in JEE Advanced as well

You should try to get more then 125 marks in JEE Main general category to get NITs and IIITs. as you said you are from OBC category then you have to score atleast 120 to get NITs or IIITs.

With 88 percentile it is hard to get into NIT. You can go after IIIT. In any case, you have generally excellent shot of getting entrance into centrally funded university..

However, their are such a large number of state run college which acknowledge JEE main score.

Sorry to say but I'll not use any sugarcoat but you can't able to get admission in any good government college , nit and iiit with this rank. I think you should take admission in any good private college or if you want a nit and IIIT then you should start your preparation for next year.

hope this is helpful for you

all the best
