How difficult is it to get a 4.0?

<p>I can't say his name here due to privacy... I am not sure that he is Yuxi or not because I know him by his traditional name (not his nick name that people at Berkeley calls him by) ....ask a chem major that is graduating this term... the guy that I am talking about is from Thailand.. there are not many Thai doing chem at Berkeley so It wont be hard to find who he is :D..</p>
