Hello,

There is no official exact percentage but 80% questions are from class 12th and rest 20% are from 11th. However, do remember that class 11th is the base so clear and strengthen all your concept and understandings from chapters of class 11th and then only you will be able to solve 12th questions easily. I would also suggest you to solve previous 5 years question paper of Comedk as this will help you in understanding the questions that come in the exam.

I hope this helps.
