Taking a student loan is always a better option. After graduating from college, Education loans help you save taxes during the job career. Go through the interest percentage at which the loan will be disbursed and take calculated steps while taking a loan.
I think that you should try to get into IIMs first. Getting a loan for IIMs will be worth it. Still, if the return on investment is good, you can get a loan for 20 lakhs and go to one of the b schools between GIM, TAPMI, KJ Somaiya. You can talk to seniors from the above-mentioned schools to find out the usual academic, placement rate, and college life. If you think it's important, you should do it.
Candidates that have previous job experience receive an additional 10% of consideration in the GIM selection process. But that is not the aspect that will determine the outcome. You should look for ROI and placements. The average placement of GIM is INR 14.87 LPA and the average placement of TAPMI is INR 15.7 LPA.
The decision to pursue an MBA program from a private business school will depend on your responsibilities, family background, and financial strength. Apart from these, the factor that should be the most important to a poor student should be ROI.
If you consider the average fees, the course duration, and the average package during placements, you can calculate the amount of time it will probably take to pay off your student loans. You can extend this method of evaluation to the various colleges mentioned in your question, and then pick the one with not only the best ROI, but also the least amount of time it takes for repayment.
