Dear Aspirant,

Both the 11th and 12th have nearly the same weightage in JEE Mains. But12th class has just a little more weightage than 11th . For JEE Mains 11th class percentage is around 48% and 12th class percentage is around 52% . In JEE Mains and Advance the paper is made from both the classes and the subjects are Physics, Chemistry and maths.

Hope this helps.
