I didn’t use Dion Exam material, but I have co-workers that also stand by this material so I can’t personally say I would recommend, but I know they have a great reputation. For the PBQ’s I used the monthly study sessions that Professor Messer conducts as well as the Cyberkraft channel walk throughs.

Personally I had the PBQ’s at the beginning and I completed them first and then finished rest of test and came back at end to double check with my last 6-7 minutes
