Now she has finished her A-levels, Megan Pitman hopes to study in Aberystwyth.
She has always wanted to do "something impactful and really big" that usually comes with a need for a degree".
Having an older brother who told her "how much fun" university was helped cement the decision.
"I've lived here my whole life so it's really nice to go somewhere new and be a bit more independent," she added.
But 18-year-olds in the area are far less likely to go to university than in many other parts of Wales, according to Ucas data.
Neighbouring Torfaen was the Welsh parliamentary constituency with the lowest university entry rate for 18-year-olds in 2024 at 16.9%.
In Blaenau Gwent and Rhymney it was 18.9% compared to 47.9% in Cardiff North, just a short drive away.
In London it was 51.5%.
University can feel distant to some young people living in the south wales valleys, said University and College Union's Wales official Gareth Lloyd.
He said: "I'd like to see every further education college, every sixth form [travelling] to every open day in Wales and a free bus put on by the college and ideally funded by the Welsh government.
"When I was in school, we saw the glossy magazine for every university."
He added that cuts to career advice in school, combined with courses being slashed at universities struggling for cash, could damage recruitment.
"If people want to go to university but don't necessarily want to stay away, then they want something on their doorstep and that's becoming more and more difficult."
