No, it can't be possible..

Hello Shubham

It is not possible to directly jump in 12th without doing 11th, because after 10th class.. standard 11-12 are totally different as a particular chooses his/her field to work on for the future. Class 11th is all the base of class 12th. If you don't know or learn the basics only (which are taught in class 11th) then how will you study in class 12th without knowing anything from the beginning. So work on from the 11th class only in order to clear your basics of the new field/studies so that you can also give your Best in class 12th.
No school allows such to directly do 12th without
11th.

Hope this helps.!
All the Best !!!
