"Here was an opportunity that came through the door to do a Zoom meeting - doing the test again - and seemed to me to be an ideal opportunity.
"Maths is a wonderful thing and it is very easy to say you are no good at it... any opportunity to learn and embrace it, great."
Asked why he took the exam, he said: "I think the answer is why not?"
In the exam, he used a calculator and a magnifying glass to help with his poor eyesight.
He said he "wouldn't have been surprised if I failed because I could not see it very well, but with a magnifying glass it worked out well".
Sitting the actual exam was not stressful, he said.
"It didn't matter two hoots whether I passed or failed, I was doing it for a bit of fun for myself."
Asked if he planned to sit any more exams, Mr Skipper said: "No, I think that is probably my lot, I think I shall go out on a high."
The Cam Academy Trust, which runs Comberton Village College where he sat his exam, said Skipper was the "oldest person to sit a GCSE".
\u201cHuge congratulations to 92-year-old Derek Skipper on his Grade 5 in GCSE maths, the highest grade available on the foundation paper he took through our adult education programme.\n@CombAdultEd @CombertonVC \n#lifelonglearning #EducationForAll #gcses2022 #gcseresultsday2022\u201d
