US. GAAP vs IFRS because, question, otherwise, yesterday

cyber21

Quick question guys I went to the Info session last week in SF and I was told by the instructors that for the Dec L1 exam we should always assume questions are using IFRS unless stated otherwise. But I was doing some sample questions from the CFA website yesterday and they seem to be assuming GAAP for some of the FRA questions. is it because of they haven't updated the website or whats the deal ? I am a bit confused
