Hello Sashwat Satdeve..

According to careers360 rank formula, 

Rank formula= [(100-total score) * (no of students wrote exam)] /100

No of students attended are 874469.

So your expected rank will be nearly around 1,50,846.

As per previous year jee mains, any rank below 2,00,000 will be qualified for jee advanced.

So according to expected rank of yours, so you are eligible for jee advanced.

And after reservation is considered your rank will decrease even more as of now we can't predict category rank so we can't predict colleges for now.

Hope this helps you. All the best
