The ones I used were pre-ACS.
But the best thing I can suggest for you is:
- Read through the ACS, highlight any items designated as special emphasis, and know these items cold
- Find pilots who have done exams with the DPE and quiz them on the areas the DPE was making sure the applicant knew (a few of mine were weather decision making (including preparation, would you go, need to select alternates); emergency procedures including lost comms; as you descend on the IAP, what items in the airport environment do you need to see to make a legal landing)
- Work with other instructors who use this DPE and ask them to conduct a mock exam.
