On my first solo, I started up & called the tower for hover-taxi instructions and they told me the runway/circuit pattern in use, & I realised it was a different one to those I had used previously.
I shut down, walked back into the flying school and asked for an instructor to go out with me again so I could do a couple of circuits with him on that pattern before doing it myself, because I wasn't sure I would do it right, which we did.
Successfully went up on my own thereafter but completely blew the approach (low weight on my own, didn't descend fast enough) and decided to initiate a go-araound on my first solo landing, which disappointed the instructor somewhat when he debriefed later!
That was with more that 22 hours!. You'll get the hang of it...
