Who are the best professors at BIT Mesra? Why?

A relative of mine used to be a student of BIT Mesra. She and a number of her peers have chosen Mr. Anup Kumar Keshri to be the best professor at BIT Mesra.

• Professor Keshri himself is an alumnus of BIT Mesra and he was a student of the Computer Science Branch. Despite being in the CS Department, Professor Keshri was impressed by Professor P.K. Choudhary who did not belong in the department. His teaching abilities caught the eyes of Professor Keshri.
• Professor P.K. Choudhary belonged to the Mechanical Department. He taught engineering drawing. 
• Even though Prof. Keshri was not a student of Mechanical Engineering, he did a paper on Professor Choudhary’s subject in 1996. 
• In addition to that, in spite of not being a student, Professor Keshri is sure that after some revision, he would be able to take classes in Mechanical Engineering.

He is thankful to Professor Choudhary for teaching him the ‘Language of Engineers’, on which Professor Keshri did the paper in 1996. He did not have to refer to any textbook for preparing himself for the paper. He wishes to be a teacher like Professor Choudhary.
