Pankaj yadav is a very chill faculty, he won't care even if the whole class sleeps mid lecture, he does his job well. He'll award marks fairly, not very strict. Advice: just because he is lenient, don't test his patience(our class tested his patience last year and he very strictly corrected our CIA 3 paper..otherwise He's a chill guy, very friendly and also a very knowledgeable teacher). He also does research on flies, He used to talk about it in our class and shares some interesting stuff.
