Thanks for the words of encouragement. I'm not beating myself up to much, just frustrated that I didn't sit the VSE test at the right time in the right conditions...which is partly my fault. To concentrate to that level, I need to make sure that the dog is somewhere else, that my neighbour who is renovating his house doesn't start drilling holes into the wall next door and that I'm sat at a proper desk in a silent room. Very difficult to organise for me during this lockdown but hopefully, I'll make a better go of it next time.
But as I said earlier in the thread, I'm 4 months into my new job as a guard and loving it so far. My TOC is known for encouraging guards to progress to drivers. So for now, get to grips with my current role, keep on enjoying it, try to move up those links so I can do some longer distance work...and see what happens!
