I would try to find out the gouge on the DPE you're using for your ride. I had friends who had reasonable scenario based orals with a couple technical questions. I, on the other hand, had a 6 hour oral with almost 100% technical questions pretty much straight out of the PTS. If your DPE was like mine, make sure your notebook is good to go. He went as far as recommending that it go in order of the PTS.
