When I was in class 12th , I didn't know about competitive exam books which will be better for the exams , then from internet I found HC verma's Sir book concept of physics.In this book you can find a lot of best questions designed for the students with answers by HC Verma sir.After practicing this I was able to clear my competitive exam for getting admission into engineering colleges.Currently I am a student in Computer Science and Engineering department in a government college of engineering in West Bengal.
Thanks to HC Verma Sir.
