The biggest challenge with SAT style tests has been the scoring which use negative marks for questions. You would have to get creative but I'm sure something could be worked out especially with the increased flexibility in the 1.9 gradebook. I know at one point I had come up with a theoretical workaround for how you could simulate the negative scoring associated with SAT tests without actually hacking the code to allow for negative scoring. Below are a couple of things I wrote about this previously. Let me know if it helps or only creates more questions. Peace - Anthony

p.s.- Please note that I never used this in practice - it was just theory in my own brain so I have no idea whether it would actually work. Let us know if it does (or doesn't).
