Being a student of Mahendras what I saw is that did just go buy the slides they do not care about the actual education. The teachers who an experienced on have gained experience there leave their job as they are paid very low.
Mahendras is degrading day by day, as they have started recruiting the students who previously two classes from them. I too keep getting the messages of interview for recruitment process on weekly basis. What they fail to understand is that the student himself is learning then how can they impart knowledge to a class of 80 students or more.
