Guys I will suggest you people not to get noticed by the faculty or the HOD of any of the department. I am a student in chemical engineering department . once in first year due to some reason I missed few classes . I took permission from all of the faculty members who were teaching my section in that year . all the faculty members agreed. they understood my situation and they grant me leave. after I rejoin I talked with my HOD regarding this. the HOD is really worst. Mr Murthy Shekhar .he didn’t even listened what problem I have faced. he just blamed me for everything. every classes I missed. he was not granting my application even though all of the faculty members had granted. I spoke with my proctor even he tried to convince him cause I have a genuine reason even though he didn’t cooperate. . so guys be aware of Mr Murthy Shekhar he won’t help you for anything . so first of all talk to the faculty members that what can be done. if they can help you then for sure take their help but not of the HOD. and one more thing there is one more faculty named Mrs Suman Pawar once if she noticed you then she won’t let you pass in her subject even in the lab . be aware of her and don’t mess with her or else she will ruin your future.
