Many thanks TLAW, I've done all those things myself (can you get a sexually transmitted disease from testing the stall warning on a C150??).
Have you ever left the chock in and had to shut down and remove it? The alternative (apply full power and roll smoothly over the chocks) is for some strange reason frowned on by instructors.
Somehow my examiner today thought I was not a clear and present danger to the community and let me pass the GFPT. There are still heaps of rough edges to get rid of though.
Hope all goes well.
