What colleges can I get?

hey So I got 99.69%Ile in january mains 2026. Although my main focus is still advanced and I made multiple errors in mains also(about 20 marks) otherwise I might have gotten a better percentile but my curiosity landed me here and all in all I wanted to ask in the worst case scenario if both mains attempt 2 and advanced go terrible for me what would be my best options for cse?
