Let your instructor tell you when you will be ready to solo. After about 2-3 months of off and on flying between bad weather and work schedules, I was doing all the take offs and landings, snap rolls, spins, etc. and my poor instructor was standing there holding the trans. with his finger on the trainer switch getting very bored. well he had me land the plane pulled the umbilical cord out handed me the trans and said fly the damn plane. next thing I knew I had soloed. I didn't think I was ready but he knew I was. So LISTEN to your instructor I haven't meet one yet that didn't want their student to be ready and throughly enjoy the hobby
