Fee structure is normal. I had to pay 22k approx every sem 22000*6. Apart from these there were trip charges etc which is charged once in a year and not more than 1000 bucks.
Have done BBM and the course was really good was easy to understand and half of mba's course was completed during our graduation only. There are mix of subjects so there are always chances to score good on some or the other semester. Question paper used to be a little tough but isn't that hard to crack.
