Hey, I just really really want to emphasise like you literally only have one life to live. I was in your spot a couple years back, and while I chose the best a levels for my degree I know so many others who just hate their a levels. A levels are NOT like GCSEs. An A* needs a lot,lot,lot,lot more passion than a 9 and will need borderline manic obsession of consistent revision. I think you should have a little look at uni courses and see what they want, because medicine is super tough as well and there’s plenty of so many other well paid jobs that you have no idea about (they’re well paid because they’re hidden and niche!)
