Hello

According to me between these 3 institutes, i can rate them as :

1. IIT Indore

2. IIT Mandi

3. IIT ropar

Because, IIT Indore has the lowest fees among these and has the lowest cut off as well.

Indore has the highest package record among these three till now which is 28 lakhs.

the teaching can differ according to the courses you choose.

Thankyou, i hope it helps, feel free to approach for further queries.
