Hello Aspirant,

See it is quite difficult to predict your exact figure of rank because it keeps on changing every year depending upon various factors but yes we can help you with approximate figures on the basis of analysis of previous year's data.

So. If we go through the analysis of marks Vs Percentile Vs rank for JEE-Main 2021 then according to the percentile mentioned by you in the question your OBC rank is expected to be in the range of 4000-5000 .

As we go through the latest cut-offs of JEE-Main 2021 of JOSAA 6th round then it shows that you can get only EEE branch not ECE branch because last year the closing OBC rank for female quota was around 2800.

You can check out the latest cut-offs from the link given below :-

Note that the above prediction is made on the basis of latest cut-offs available on official website of JOSAA or CSAB and the cut-offs are bound to change every year depending upon various factors such as the number of candidates appearing in an examination, the number of candidates qualifying an examination, difficulty level of the paper, and so on.
