What they are probably getting at is that you have no evidence of recent study.
I'm 40, did a levels in 1994. Graduated from my first degree in 2001.
I spoke to the course admissions (for current degree) who said I had no evidence of recent study, which I did actually have as I've done 3 level 3 courses distance learning, but he suggested doing an open uni module to show I can still study at a higher level and it's MUCH cheaper than access course etc.
I showed I could study while working and raising 3 children, he said I'd find the first year of Uni easy if I was able to do that 😂.
I was told in 2004 that there's a 5 year cut off for qualifications. You still have them, but you still need recent study evidence. That was Birmingham Uni telling me that.
