NOT AT ALL GOOD FOR KAS!
Don't know how it was, and may be its good for IAS coaching, I really not satisfied with KAS coaching, In fact it is one of the worst coaching center I felt. Except History and Polity, coaching is no good for other subjects, inadequate knowledge/unclear for the coach themselves, I felt I know more than what they are teaching. And its infrastructure is very poor/worst (no good toilet and water facility).
And Books wise, Geography book which they have provided is complete copy paste NCERT BOOKS, that too without proper alignment of topics and Headings. Economy Outdated...
It is better to buy books (like Khullar or NCERT(Geography), Laximkanth and DD Basu (Polity), Ramesh Singh(Economy) and Spectrum( Modern History )) and STUDY @ HOME rather JOINING Universal Coaching Center for KAS.
As of now, it may be good for IAS (that too not sure, I have not exaperienced) as Tutors from Delhi used to come and teach, but NOT GOOD FOR KAS!!!
