It depends on many factors

> No. of students appear on exam day.

> Minimum criteria to meet or cut-off.

> Paper style (Easy / Hard).

Hence it is doubtful to give the exact rank but according to previous year it will be around 15k to 25k

Note: if you are a GEN category candidate, you won't be getting good private colleges as well.But most of it depends on the result and percentage of students scoring higher marks than you plus many rounds of counseling may provide you with a better choice .if you are lucky you will get a good college and later you can change the branch you want.

Hope it may help You .
