So, i recently purchased two books the reason to give 3 stars is the book is very good but in one of the books i think english one, the pages are not synced properly and the pages are miss attached to where they should have been.... I kindley request you to look into it or send another pair of book before taking this one as i have my exams coming up so i cannot return it right away i have not marked any sort of writing till now i want you to contact me in my email if possible.... Otherwise its the best book money can buy.... All the best ppl

Solved papers are well-arranged chapter-wise and really helpful in preparation.

This book helped me a lot in understanding the pattern and types of questions asked in CDS.

Solutions are to the point and the coverage of 12 years makes it reliable.

Using this book daily has really improved my preparation and confidence.
