"First of all there are good & bad things about these book.1. Books are easy to understand which helps to complete topics in vedy short time.2. Also it includes questions and answer with different levels.3. Previous questions of PCS/UPSC exams are also included in the relative topics which is great.4. But disappointing thing is there are some of points are missing from NCERT. Also one can find little mistakes in answers."
