Why do you feel so offended if you know you tried your best? Maybe subconsciously you might be thinking you did not do your best? But i'm sure you know best. Not trying to imply anything. I'm sure i do things wrongly at some point of time, but don't tell me you deny that your batch is not working hard enough? You say you beginning to hate my batch. But have you thought why i even bothered typed this out? It's because our sl is always "busy" and don't have time to teach you. Like someone mentioned, so what if one person puts in his/her best? It would not help is his/her peers are not thinking the same. It's a joint effort. Keep hanging on.
