I follow R.D Sharma from class 9 to class 12. I found a variety of question and also a good collection good from zero level to higher level. First, I would like to tell that the R.d Sharam book is the best book for competitive exam like NTSE, Olympiad etc.
For those students who only prepare for the board exam, then please don’t go through R.D Sharma because R.D Sharma book conation a lot of question which is necessary for the board exam. Students who only prepare for board exam that student can buy R.s Aggarwal book and also solve NCERT book.
If I would like talk about the style of printing that is not so good because R.D Sharma book paragraph to explain the concept, which is good for the student in a such a way that if someone who read the same things in points then it takes less time than the paragraph.
