I have read all CBSE books thoroughly during my school days. Consequently I scored 99/100 in Science in 10th grade and was amongst India's top 1% students of science. I took up science further and presently am a Graduate student in Theoretical Physics of Fluids. However, the charm of CBSE textbooks never left me and even today I have the physics texts with me. The class 10th Science book was arguably my favourite. I would love to go over it with you again.
Apart from reading these books myself, I have helped out many junior and my younger siblings with their studies. Hence I've read these texts several times. I have been teaching students online and face to face for about four years now. I have also seen ICSE and few state board text books for the sake of comparison. Overall I've seen a fair bit of educational texts in India and can reliably attest to the standards maintained by CBSE.
The curriculum , the methodology used, the esteemed reviewers involved in the publication and the intrinsic values of scientific thinking that the authors have brought in the texts stand unparalleled from any other textbook in the market.
