Richard, yes they do give you time for a 15 minute tutorial on how the computer based test will work that isn't included in the 4 hours exam time. Not knowing for sure if it was ethical to use tutorial time for the brain dump, I felt doing the brain dump was part of the test, so I didn't feel right about doing it during the tutorial time. No one would have really know, but I didn't feel right about it.
Also, on some of those formulas, depreciation, communications channels, rom, six sigma and depreciation, I have used them many times before or was comfortable enough to recall them off the top of my head, so I didn't write them on the brain dump. If I would felt nervous about the test where I would have thought I might freeze on the test I would have written them down also. But I felt fairly confident on those formulas.
