Applying with a high SAT and a GED

I dropped out of high school (long story as to why, not sure how I would tell it to colleges), but I have a 1540 SAT and a 3.75 GPA from before I dropped out. I haven’t taken my GED test yet, but practice tests have shown that I’ll do well. What tier of colleges should I be applying to? How do I go about presenting this?

I was also exceptional academically until around 10th grade, where I started to get 50% B’s. I dropped out in 12th.
