First solo circuit was around eight hours (don't have the logbook in front of me), the instructor indicated he was happy with my skills, but not with the wind so I spent an hour hanging around the club waiting for it to calm down. Then went and did another couple, taxied back to the club to let the instructor out, and went out and did it on my own.
When you're not used to it, it is suprising how well the 152 climbs without the instructor on board
