I have been looking as well, but can't seem to find one particular source. Gouge sites have multiple questions written up in them, so read closely and you should find some questions that will appear on their exam. I recently took the ATP written so I am hopeful that this will be helpful to me.

Does anyone have an update on what PSA has for classes scheduled? Any new-hires care to add anything about their training, quality of life, etc. Anything!?

Thanks!
