I went solo in under 10 hours too, but covered stalling, spinning, EFATOs, PFLs, and glide approaches first! I knew I was going to be sent solo because I felt ready, my landings were good, and consistent, and we did a circuit with simulated radio failure (with the tower flashing the green light at us).
I think pretty much everything that was likely to go wrong was covered, my instructor waited on the taxiway with a handheld transceiver, no-one else was in the circuit, and there was hardly any wind.
Nothing went wrong, but I felt confident all the way round that I could handle it, or at least make a good attempt at doing so, if it did. This meant I enjoyed it more too.
