great sir, they dont teach anything in classes, if u have the power please look into it, we cant openly complain about this in the college, but in most of the subjects the teachers dont even have basic knowledge abt the subject, and i am not baselessy accusing, for last 4 semesters almost i myself have experienced this, in some classes even i had to tell the teacher about the topic which they then teach the whole class, so unless someone like you who is passionate about the subject teaches it feels pointless to attend classes for attendance, the cirruculum is good but the teachers are not apt for it, except some senior teachers or some passionate ones like yourself all of them just do the formality of talking for an hour in front of the class, i would humbly request you again sir please look into this matter, you know what university i am talking about, also thanks for this channel hope you read this comment
