I think I waited about 2 weeks from my phone call to my assessment. As for revision, they seem to like principles of flight questions, especially stuff about the effect CG position has on range, stall and spin characteristics etc, centre of pressure and wing sweep. Apparently they also ask some basic questions on the 738, like wingspan, range, engines and they're power, MTOM, no of pax etc though I didn't get asked any of these. I also got asked about the atmosphere, how an ASI worked and what would happen to it if the pitot probe was blocked in a climb/descent.
