For context - had my DD when I was very young. Have three decent a-levels in generic subjects. Worked in random, uninspiring jobs my whole life. Now that DD is older, I'm considering finding a uni that does a degree where I would get QTS at the end of it, hopefully one nearby, and becoming a secondary teacher. Has anybody done anything similar? It seems crazy to me to even consider it, but I'm in my 30's, so surely young enough for it to be worthwhile!
AIBU - don't do it/retrain in something else
AINBU - go for it!
