It will cost you around 15–18 lacs if you join this year (personal expenses not included). [There are scholarships to avail].
Here is a brief outline:
The fee keeps increasing each year (sadly).
I have just completed my 2nd year, and I will have to pay a fee of 1.67 lacs for my next semester. The fee can’t increase between semesters. I had paid 1.47 * 2 lacs in my 2nd year. At the time of admission you have to pay roughly maybe like 30–40k (you can check that on the official website).
After your fourth semester, you also have to do an internship program (called PS) which costs you 40k (presently its 40k).
Apart from the semester fee, you will have to pay an additional amount (around 20k per semester) for hostel, electricity, mess, etc.
Also, the fee is slightly different in the three campuses (mess fee, etc), but its not much. (I am not talking about Dubai here please).
