I ordered this book about one year before and I finished it in about 4 months. I have read it many times since then. It has all the important points in history covered which makes it a must for various govt job exams.
The printing and paper quality is very good. The book is still in good condition. It has extra bonus GK which they have added in the end which it's very good for quick revision before the exam.
I am very impressed by the book. Some of the dates in the history section is different than other books but still you can confirm that from various GK sauces on Google.
Overall it's a must but for Govt exams.
