I took an admission for AWS Architect. Faculty-Prashant was too disrespectful to me. When I was asking any question, he was not responding me and on the contrary, he was insulting me . If he can't answer about my question, how can I learn or understand further topic. He may be knowledgeable, but if he has attitude problem with students, than he is big Zero. When I point out that he is not respecting people, he said that if I feel like that, he can't help. I have to leave my lecture from half of the way, because I could not take his more insult.
Since there is no option of putting Zero star, I am giving 1 star.
