Mum went back to uni when I was in primary school and got a 1st in maths bsc.
I didn't ever ask dad exactly what qualifications he had (he died when I was 9), I believe he had a couple of gcse equivalents, then mechanic and carpentry qualifications and some hygiene ones relating to being a butcher. Basically mums very academic and logic and dad was always a practical problem solver, I ve ended up a bit of both.
