Dear aspirant !!

Hope you are doing well !! Beleive me if you can't afford heavy and expensive books more than 800 rupees then the best one for you is NCERT . You can get it from anywhere at nearly 200 rupees for each subject . It is the best . Even directly question comes from it . Student don't matter whether he is financially poor or rich must use this book . You will top the exam by using ncert only . I have applied the same at my time .just believe me .Even nowadays jee main and neet question comes from ncert .

Hope you will understand !

Thanks
