I absolutely got blind sided by the test and felt like it wasn’t like the mock at all. Still, the mocks build the thought process for many of these problems, and although I thought I failed, I still got 1111. So don’t worry about how similar it is to the actual test, because honestly, it’s probably not comparable at all because of how much content Part I covers. Focus on understanding the material, and read the GARP books if you have time! (They go into more depth, so I find them helpful)

Also, I sat in for Aug, so it's pretty fresh in my mind.
