this book is as a guide but it's very very useful. I have got 95 number in class 12th with the help of this book. this book does not have detailed chapters they are in a short form but every other thing is very detailed and very very helpful even you don't need to buy any question bank (guide) if you have this book.
I have use highlighters on a lot of places and written a few things but I am so those will be helpful for a student. good luck for your new class💞✨
