That was a good one but we'll fix it now :)

Thank you!

Btw, just thought I'd hijack this moment to say how much I appreciate the moderation work you do here, it's fine art, and HN seems to get it about right most of the time, which is all we can really ask.

With respect to your question, I did something similar, getting decent A-level results but then, er, having other things to do for 10 years. I went back and worked through my A-level textbooks again at 28, I found it quite helpful knowing "that I had done this before" and I think it got me back up to speed quite quickly (a summer).

Yeah, I definitely think that will help. I've had the same experience when trying to get back into running. Knowing I used to run a lot makes it a lot easier getting started all over again.
