I’ve added typed solutions for the Fall 2019 sitting of the exam. If you want to appeal anything, the appeal deadline is Nov. 11. I’ve added notes in some of the problems about what I think they may or may not do with an appeal, but just because I don’t think an appeal will succeed doesn’t mean you shouldn’t do it.
The questions I found most problematic are #38, where statement I should be about splits rather than trees to be true (I could see them going either way on this one, or maybe accepting 2 answers), #35, where the given information is contradictory but I still think there is a best answer, and #34, which I think should be thrown out but they may stick with C.
If you have any questions about these or others, posting on the discussion forum is easier for me to respond to than blog responses (which tend to hit spam filters). If you want help with an appeal, let me know.
