Currently in UK, is uni in US target school feasible?

I kinda think the title sums it up, but can I realistically make a target school in the US? Right now, I’m predicted all 8/9s under the new gcse system, and my school has started predicting a-levels too (we’re tryhards like that). My a-level predictions are AAA, with scope to rise/fall. I’m a smart guy, I’ll probably get better than AAA. I will definitely be doing the SATs at 17. I did one last week with no prep and got 1460. I really hope this doesn’t come off as a giant brag-fest or some shit, I really just wanna know the likelihood of moving. Thanks.
