Hello student

For your need of Q&A books, the publications are  Jeevish, Jen, Don Bosco, Dinesh publishing, and Arihant also.

It will be better for you to consult with your subject teachers and make a decision  to buy books .

But my suggestion is go through your textbooks thoroughly it will be  more than enough to secure more than 90 percent in 2nd PU exam of Karnataka State Board.
