I was talking to my DD last night about o levels and GCSEs. I did o levels, in 1987, which I think was the last year. But in maths I remember doing a different exam called 16+ which gave me an o level at Grade C. I’d missed a few months of school due to glandular fever and was never fully able to catch up in maths. I suspect I was a borderline candidate as a result. I think this must be why my school suggested this alternative exam. Can’t find out much about it online. Does anyone else remember 16+?
