Bad IGCSEs and Good AS Levels -- Any chance or good unis?

So I scored a 4Cs and 2Bs while I was expects strt As.
Let’s say I choose 3-4 subjects in my AS Levels, and score all As or at least 3As and a B, and an SAT score of 1400+, what college options will I have? Are there chances of getting into a good college in the US or should I stop trying at all if there aren’t?
