I am not going to talk about my performance, but I have some opinion about these two types of personalities. I have observed that introverts can be very quiet people who hesitate from participating in anything but a good factor is that they can be great performers if not great talkers. I mean, an introvert might not answer questions in the class but he might be really good at writing down an answer … may be better than an extrovert who speaks a lot to respond to the teacher’s questions in the class. What do you people think ???
