I am seriously thinking about starting a correspondence course to get a B.Sc. and eventually a M.Sc. in computer science. But I still have time to decide. I can apply in December and semester starts in April.
Since I would do it part time the Bachelor would take six years. Maybe one year less because I might be able take two courses from my previous degree ( masters degree in Japanese Sciences with a lot of economics courses). But it will still be a lot of work
But I think it would be worth it and would enable me to advance more in my career as a sysadmin or maybe make it easier to switch over to DevOps or so.
