No, I don't think ITM Mumbai is worth taking a loan. The high fees do not do justice to the meager packages received by the students. Despite recording 100% placements, the average is as low as INR 8.5 LPA. It’s better to go for an average institute with low fees. The low packages you will receive will be worth the low fees you invested.
IMT Navi Mumbai placement cell ensures placements but does not guarantee a good ROI. So the best way is to look for an institute that charges low fees and gives enough ROI. Only then it will be worth a loan.
