In the meantime I ' m sitting in the lounge passing time before my class starts at one . So far so good I had a version of this class in under grad and I got an " A " then . It concerns me a bit that there will be group projects and there are 3 people that do n't speak English well and they seem to give the impression that they know it all .
According to the above context, answer the following question.
Why does having taken a version of this class in undergrad make the speaker confident about the current class ?


None of the above choices .
