There are 2 books part 1 and part 2..which covers class 10th science syllabus with detailed theory and has a lot of questions and test papers for practice.
The condition of this book is a bit old and is based on old ncert but it is very helpful for board exams and you can use it for Olympiads like nso too as it contains deleted chapters of ncert too:)
I have listed the price 150 which is very reasonable price as it
contains books with mrp 300 rs each.
