Hello Aspirant,

Let me give all your answers in sequence ;-

So If we go through the analysis of marks Vs Percentile Vs rank for JEE-Main 2021 then according to the marks mentioned by you in the question your percentile and OBC rank are

>>>>>>>>  expected to be in the range of 84-90 and 28000-32000 respectively .

Note that the percentile and rank which are predicted are only the expected percentile and rank on the basis of previous year's data so your actual percentile and rank might vary depending upon current factors.

On such OBC rank any of the NIT is tad difficult. But you can go for some other colleges like :-

Sanjivani College of Engineering, Ahmednagar

Bhopal Institute of Technology and Science

Trinity Institute of Innovations in Professional Studies

Barkatullah University Institute of Technology

On such percentile range and being an OBC candidate you have good chances to qualify for JEE-Advance 2022 but still the cutoffs for this year have not released yet officially.

As the cut-offs are released along with the JEE-Main 2022 result so for now you can get an idea from JEE-Main 2021 qualifying cut-offs that are enlisted below :-

==>> Common Rank List (CRL) - 87.8992241-100.0000000 Percentile

==>> GEN-EWS - 66.2214845-87.8950071 Percentile

==>> Other Backward Classes (OBC-NCL) - 68.0234447-87.8950071 Percentile

==>> Scheduled Caste (SC) - 46.8825338-87.8950071 Percentile

==>> Scheduled Tribe (ST) - 34.6728999 87.8474721 Percentile

==>> PwD - 0.0096375-87.8273359 Percentile

Note that in above table it is not the actual cut-off for JEE-Main 2022 but previous year's cut-off.
