I am shy person and I don't participate in the class. It doesn't mean that I don't know or study. The reason is that I don't feel comfortable while talking in front of crowd. You can say that I am an introvert who hates to share his feeling knowledge and emotions with others. I think that f i know something why i have to share it with the whole class just to earn few marks.
secondly i feel hesitation while having conversation with someone who speaks English. It doesn't mean that i cant speak well. The reason is that i don't have enough vocabulary which would support me in having long conversation. This is my weakness from the very first day i entered university and due to this i am not able to explore my self in a way i should.
