Dear Harsh,

The All India Council for Technical Education (AICTE), the statutory body for technical education, has revised the eligibility criteria for Class 12 students aspiring to pursue engineering courses. According to the Approval Process Handbook 2021-22 (https://www.aicte-india.org/sites/default/files/approval/index.html#p=1) , subjects such as Mathematics and Physics will not be mandatory, but optional, to get admission to undergraduate programmes such as Bachelor of Engineering (BE) and Bachelor of Technology (BTech). But NITs and IITs are independent of the decision that AICTE takes about the curriculum of engineering and technology courses. As a result of which, you need to have physics, chemistry and mathematics in your higher secondary. Now that you didn't had mathematics in your class 12 you aren't eligible for getting admitted in NITs and IITs. In order to be eligible you have no other options other than to repeat class 12with mathematics in the lists of subjects with physics and chemistry.

Dear aspirant !

Hope you are doing great ! You have done mistake ,for JEE mains you have to have subjects physics, chemistry and maths ,as a pcb student you are not eligible to appear for the JEE exam ,so you have to re appear for class 12 with pcm if you want to appear for JEE mains ,no other way will work here.

Hope it helps you !!

Thanking you!!
