Which one is a better college to pursue an MBA: LBSIM -Delhi or BIM-Trichy?

This is always a tough question to answer. You can consider a number of assumptions in order to shortlist the business school you would like to go to. You can compare the one you like to them and make your decision:

• Assumption 1: Business schools presently are student-driven and this mostly has nothing to do with the faculty, infrastructure, or even the knowledge capital for that matter. The classroom is the place that will facilitate you with all these opportunities and knowledge will be disseminated here. This needs to be applied to activities outside the classroom as well.
• Assumption 2: Alumni are an important factor for colleges. Because of alumni connections, a lot of places like FMS, JBIMS, IMT Ghaziabad are quite well-known business schools.
• Assumption 3: Part of who you become also depends on what activities you choose to pursue in college. These include clubs and committees, business school events, or if you choose to only focus on academics and get a good CGPA. This will surely help you get good placements.
• Assumption 4: Sometimes, the location of the school will also play to your advantage. For eg. Mumbai or Delhi located B-schools.
• Assumption 5: You should also know that rankings do not matter for the top 10 to 15 schools.
• Assumption 6: The placements are dependent upon the alumni base and past history. Most companies that come for repeat recruitments are usually less than 50% for most business schools. Every year it comes down to reinvention and it boils down to the alumni. But, in reality, placements are hard work and luck with a 30:70 ratio. There are also the usual perceptions that some schools are better in marketing and others are good in finance, etc.

You should choose wisely and make your decision accordingly.
