I got 37 percentile. I did 27- 27 questions in math and chemistry. And22 in physics.but marks are good in physics. What's happened wrong me

Hello greetings

Attempting many question does not guarantee that you will get more marks because there is a negative marking in JEE main and if you attempt question wrongly then Instead of giving you any marks your marks will be deducted therefore important thing is that how many questions you solved correctly so in your case it may happen that you have solved more correct question in Physics compared to mathematics and chemistry and also the percentile scores does not indicate marks it indicates your relative position among the students will it may happen that the physics part was difficult compared to others therefore your percentile score will be high in it.

Hope this helps all the best
