Hello,

It doesn't change any thing if you taking 5 subject or 6 subject in 12th boards. The main thing in jee mains criteria is to fulfill the 75% marks requirement in 12th boards. If you are getting 75% or more in 12th boards with 5 subject or 6 subjects , you are eligible for JEE mains admission procedure. So, try to aggregate your marks to fulfill the requirement and try to score more than 75 on PCM.

All the best. Hope this much information will clear your doubt, for more queries reply here.
