Astrophoria foundation year

I've been considering applying to the Astrophoria foundation year, and was wondering if anyone would be willing to share their experience applying? I'm really worried because I'd be applying whilst on a gap year, so I have achieved grades, and I'd be doing it on my own, especially because my whole family actively opposes me going to uni at all, so I don't really know what is going on. I don't know if applying with achieved grades would disqualify me from applying, as well as the fact I did apply and had an Oxford offer last year, but missed it. I am eligible based on what I can tell from the website, but I don't know if I'm as affected by the criteria as I should be, if you know what I mean? Like I feel like even though I'd technically meet the criteria, I don't know if I'd deserve to apply because I don't actively think about how much the things I'm eligible for actually impact me? I mean, I think they might have but I don't know for certain yk? Ik this isn't something anyone can determine based on what I write here, but I was wondering if anyone else has applied / is applying with similar concerns and what the process involves. Thank you

If you meet the eligibility criteria and have the grades, you can absolutely apply. Applying when you have already achieved your grades will not at all disqualify you. Good luck!
