During my academic contact with Dr Hariharan, he was a straightforward lecturer, that is whatever is in the milestone, we did and nothing else, he did not take much time during lectures, and it was easy to understand him, because he didn’t confuse us with unnecessary materials that weren’t on the syllabus. He also respected time a lot, because during his 7 am lessons he allowed 10 minutes late but during midday lessons he chased people out who were late. He also advised us a lot about life after tertiary school, he also encouraged us to work hard and pass; he did this by giving us examples of students he taught before who were successful because of his help.
