Which guide books are best for CBSE Class 9/10?

Being a student of CBSE Class 10, I want to suggest the following things :

In every aspect, Arihant's All in One is really really helpful. It is far better than that of Xam idea, evergreen, together with or any other publications.

And I can tell you why : 

First, It does not contain only the sample papers and previous year question papers but also deals with all the important topics discussed in NCERT Book in a sequence wise manner (unlike Xam idea/other publishers)

Second, it gives a piece of complete information about the syllabus of the current academic session in a really understandable manner that which chapters are going to come and which ones have been excluded. So go with Arihant's AIO and become doubt-free about your syllabus.

Added to this, it also deals with 'Top Tips and Tricks for writing answers in examination' which boosts the confidence level of students 🚀

And the most lovable one, it does not contain any extra/additional information rather than the NCERT BOOK!

So if students use this guide properly, i.e. after going through the whole NCERT BOOK, it will be the most enjoyable academic session for them and they will definitely achieve good grades in the Boards!
