I did my first solo at EGTC (Cranfield) a few years ago, landed on 21 a tiny bit long but too late to exit at Charlie, so I announced I was exiting from Echo. I now know that I should have requested this rather than gone ahead and done it.
Probably why I never got a "congratulations" or a "well done" from the tower!
