Hello student,

Yes, you can go for 11 th class as a dummy and join some coaching institute to prepare for some entrance exam.

As a lot of students every year opt coaching centres as thier full time and put thier school as secondary. Just for sake of clearing board exam.

But, For you I will advice you to go for one partucular coaching centre and don't rush between two of them either  AKASH or ALLEN.

Hope it helps. 

Thank you  :)
