Physics and Electronics A-levels, so a certified geek. Also Maths and Chemistry, but with embarrassingly bad grades.

Handwriting is utterly illegible block-print, which only really gets used for labelling things with (yes, black) permanent markers these days. Computer Science degree trumps the geeky A-levels in the bad handwriting stakes (I believe only medics have worse handwriting). Also suspect the obvious link to socks & sandals makes Audaxing inevitable
And I did once have a Cycling Proficiency certificate.
