One of my friends from school used to be a student of the NIT Calicut. I can share his experience at the institute.
My friend advises that you should expect the coursework to be rigorous. The institute also plans occasional trips to Ooty, Kochi, Goa, etc.
NIT Warangal has collaborated recently with ABB Power Grids India which will help in the creation of reliable and clean power. The launch of a unique Master of Technology in Smart Electric Field is a part of the said collaboration.
NIT Warangal also offers MBA programs that are part-time in nature for working professionals. There are 13 specializations along with an option for extending the duration.
