Where on UCAS do I put my other qualifications?

I have the qualifications for a qualified bike mechanic, as well as a first aid course, and a mountain bike coaching qualification.
Where would I mention this on ucas?
The “extra activities” looks more like it has to be to do with the uni course I’m interested or similar.
Or do I just mention it in the 3rd part of the personal statement

I guess - but surely it would help me stand out no? Being a trained bike coach / mechanic

Har de har har. Electrical and mechanical engineering

If they see 2 students both with 5As how will they tell the difference between :
Candidate 1:
Got 5As, 1 minimum wage job at the local restaurant
Candidate 2:.
Got 5As, has a passion and followed through, got qualified to become a mountain bike coach after being offered a job because of helping out doing a work experience. As well as being able to get a job at a bike shop where ever I am with a nationally recognised certificate- being the youngest person ever to hold such certificates?
Hmm yea I wonder why that would possibly look good? 🤷*♂️

Not if it’s a highly competitive course

Not if it’s a highly competitive course

You’re implying that a university would give preference to the wealthier student who had the privilege to devote substantial amounts of time and money to their hobby over the student who was forced to work all their free hours in order to help pay their family’s rent?
It’s an academic course. Admissions decisions are based on academic ability and potential not on non academic hobbies.

Hi, experienced admissions staff here. They absolutely would make offers to both in the hypothetical scenario.
I’d recommend that you have your ref make passing reference to the extra stuff, (you’ve got limited space in your statement). From your POV you should be focussed on your suitability and motivation for the academic course at hand. Super-curriculars are a very welcome way to do this, but extra curriculars will just be skipped over as they’re not relevant and aren’t a fair way to assess candidates.
