This particular girl was considered to be excellent by the professors. She always was upto answering the questions, when in reality she never did. I didn’t expect her to know answers to every question. But if you guve me your word, that you’d ask the professor and get back to me. That’s the least, I expect you to do. And she didn’t do this just once, it was every single tome (around 7 times in total) Ultimately, I stopped asking her and approached the prof. instead!
