My cousin was a student at IIT BHU in Varanasi. She shared her experience as to why she thinks it’s not a good branch for Mechanical Engineering.
The professors are under qualified here. They have little knowledge about their own subjects and teach only bookish concepts. The classes are boring.
Students attend classes merely for attendance. This is because even if you score good marks, you might fail if your attendance is less than 75% in that particular subject.
The numerical answers are not checked through the stepwise method. That is your method to solve has no value if your answer is wrong.
Professors here are not well versed with the relative grading system. This affects the CGPA of many students.
Placements are mediocre here. Only non core sectors like coding and analytics get placement opportunities. The salaries offered are also very low.
Labs are not equipped with modern tools. The students get no practical exposure.
The conclusion from her experience was that the professors in Mechanical Engineering at Varanasi IIT are bringing down the results of students terribly.
