Context: 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 ?
Option 0: Because , since they 've already taken the course once , they wo n't have to buy another textbook
Option 1: Because they had the same professor for both classes so they know how he grades papers
Option 2: Because they saved the answers to all of the tests and quizzes and should be able to pass once more
Option 3: None of the above choices .
Answer: 3
