Everybody must have heard of M.V. Kamath. I took the electrical transfers course under him. He was an understandable teacher. I attended all his lectures, in the final exam got upended by Karmarkar, and as result Narendra Karmarkar got an A, and I an B.
I was unhappy and went to him about the grading. He said that in a class only one genius can be there and blah blah blah.
Mukherjee loved to fail everybody. Just one A, one B, and the rest fail. He got a heart problem right before he was planning to punish me for attending IIT Bombay and was hospitalized. Barely escaped.
These teachers prove that IIT professors are stupid. Destroying entire country by their grading. No professionalism.
