More stalls, (the 172 is harder to stall than the 150 and better behaved when it does) both power off and power on, then S-turns, which were kinda hard to do because the wind was variable and gusting. I got it right at the end, but the wind was causing me issues for most of the turns.
One approach with a go around and then one landing. I still need more practice taxiing.
I am, however, getting more comfortable and some stuff, like holding altitude and heading is easier and more automatic now. Less thinking, as it were.
I think I am getting this, if slowly.
