Hi Heeramani,

Since you have attempted both the JEE Main Sessions, best of the two percentile will be taken while calculating your final rank,(i.e. 64 marks in April session). After considering this marks, your probable rank is approximately between 146143-166143 and your probable category rank will be approximately around 45523-49523. Since you belong to the reserved category you might have around 25% chances of getting a government college but your chances of getting a branch of your choice is almost nil.

Hopefully this was helpful.
