Hello Saketh,

      For a percentile of 73 in jee mains you would be getting a rank in the range of 2,60,000 to 3,30,000.THis was calculated from this link-https://engineering.careers360.com/percentile-predictor-result/1094?s=14932541801553586908

So with this rank it is difficuilt to qualify for jee mains considering thay your oc.Also for jee mains qualification you should have scored more that 75 % in your 12th board exam.

But dont worry there is a exam in April for jee mains where you will have a second chance to crack jee.

All the best!!!
