The leading B-schools in India include IIM, IXB, XLRI, FMS, JBIMS, IIFT, MDI, IMT, NMIMS, and SIMBM. These are well-reputed institutions that were established 30 years ago. Recently, IIMs should not be under consideration as they lack good infrastructure and effective classes. That might turn a bright student into a dumb one through exposure to negative vibes.
When it comes to the Great Lakes Institute of Management, it is also poor in terms of academics and campus atmosphere. If you are strongly passionate about the field of software, as they are relatively better than others, then opt for Great Lakes.
So, it is better to wait for your upcoming results and choose any one of the aforementioned leading B schools in India.
