I have a friend who completed his MTech in Civil and Infrastructure from IIT Patna and he shared his experience of the same with me.
Course structure: The curriculum was poorly structured and failed to provide specialized knowledge in any area. The subjects included Environmental Engineering, Railway Engineering, Structural dynamics, construction planning and management, reliability, economics, etc. The mixture of subjects made it a jack of all trades but a master of none.
Faculties: The faculty pool here is miserable and most of them are old people enjoying their life with government funds and facilities. They rarely take classes and when they do their pedagogy is pathetic and even the most difficult topics like Reliability, FEM, dynamics, etc. were poorly taught.
Research: Comparing the research culture here and that of other IITs you will realize how pathetic the scenario is here. The reason was the lack of faculties’ research capabilities. Neither were they involved in any research work nor did they promote it to the students.
I really hope actions are taken against the falling standards of IIT Patna and the IIT standards are restored.
