My role is becoming increasingly technical. I'm mid-40s, and luckily surrounded by technically minded people both at work at home but I think I would benefit from a better understanding of computing and computer science. I'm wondering if doing a distance learning/online GCSE in computer science might be a start. Has anyone done this or similar and offer any insights into good providers etc? Or thoughts in general. I'm not looking to become a programmer. I just want to better understand computing systems and architecture (I think!).
