Teong,
relax man ! But, I think I understand the feeling, sometimes, the lecturers impose their principles and opinions on us, without actually knowing where we come from. And, there are people, who are insensitive to other people's peculiarity and individual strength. Kind of selfish la, actually. Since last year, i learn to put myself in others' shoes, not everyone is like me, not everyone would share the same strength as mine, and not everyone knows my own pain and labour.
But yes, you should be proud of yourself,... don't be angered man !!
All the best, buddy
