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 .

Question: Why does having taken a version of this class in undergrad make the speaker confident about the current class ?
Answer: Because , since they 've already taken the course once , they wo n't have to buy another textbookNone of the above choices .Because the courses cover very similar material , so the current class is not too intimidatingBecause they had the same professor for both classes so they know how he grades papers
