Help on whether to apply to Oxford or not

So I'm currently doing Maths, Economics and Chemistry and I did Biology during AS level but dropped it before end-of-years. I recieved ABB and most likely will be predicted A*AA, which meets Economics and Management's entry requirements and is one grade above the entry requirements for PPE. I truly think I could get A*A*A in my real a-levels as I go to a really competitive school (literally everyone wants to be a doctor/dentist/lawyer).
I'm not sure if I should use one of my five spaces to apply because I've been fearmongered into believing that the only people they interview are people who receive all A*s.

I got good grades in my GCSES where I went from being predicted 8888666665 to 9988888887 with a jump from 6 to 9 and another from 5 to 9. The problem is I compare myself to my school peers a lot and a lot received all 9s at GCSE and loads are most likely predicted all A*s which makes me rather worried.

Is there anyone who can give me advice on whether I can still compete for a place as I've done a fair amount of super-curriculars?

Plenty of people receive offers without all A*s at A level or 9s at GCSE. They care far more about the TSA and interview scores. People really exaggerate how elitist Oxford admissions are, you'll be fine.

Thank you, I tend to be a bit jittery since ik a lot people in my year want to apply as well. I'm visiting oxford tomorrow, do you think I should ask how they score interviews, or is that perhaps too forward?
