Thus is a binded book of Science Class X CBSE chapters , each page has been xeroxed and has case studies , MTFQ , frequently asked questions , etc . It will really help for your 10th board preparation. I have also attempted few questions . Don't spend each and every minute framing sentences as ans but answer the question with words ( TRICK ) . We hope we can give quality education at lesser prices , thank you . I earn very less after all the deducted price but I hope atleast someone is happy because of me . Hope this book helps you :)
