IMS learning resources is one of the well known coaching center in India for MBA entrance exam.
Good things about IMS:
1) Test series level is very good.
2) Good administration
3) location is good near to metro station.
Bad things about IMS:
1) Faculty is not that much affective
My suggestion to all cat or similar exam aspirants choose its test series and choose some other coaching center near to your home location.
MBA entrance exam is the exam where examiner are searching your ability to tackle complex problems so work on that.
BEST OF LUCK!
