The Self-promoter.

"My BE project was best in the college" or "I am doing a PhD currently in ....". This kind of professor spends more of the class time promoting their own achievements rather than teaching the subject at hand.This professor will take every chance to remind you of the one time they were published in that random journal you’ve never heard of but is, apparently, a big deal. When you ask a question in class, they will respond with a chuckle and put on their best patronising tone and lead it to an example of their own excellence.  How to get through this: Never ask questions that will definitely lead to more elaborate descriptions of obscure things.
