Hi everyone I left the UK after year 8 and moved to a different country and want to move back to the UK now that I've finished secondary school abroad but I never did GCSE's (meaning I can never get a job) since I left after year 8. Could anybody help me?

If this post wasn't appropriate for r/AskUK could anybody forward me to where I can ask?
