So you are 66 out of how many kids?
The loads with As (uw 4.0) is a common phenomenon that seemed to get worse with covid. There are schools that have 1/3 or more kids have all As. But the weighted and the choices of AP and honors classes can tell some of the differences. Other schools weight honors-AP-DE the same so you can be near the very top or at the top of the school with weighted and yet have skipped out on the rigor expected for your HS. It is too hard to tell from the outside, but considering you know at least a handful in the 4.7-4.8+ range makes me think that in general T10 acceptances would come from that group. Maybe T20 too but that depends on the HS track record of acceptances. Even though you have definitely challenged yourself, relative to your peers you are not in that top group of uber-rigor kids. Also, for a Biochem major interest with a 2 on the AP chem test, that gives me some pause and the AOs may also pause a bit with it.
Try not to worry about what you cannot change and think of it this way: those uber-competitive classmates may not be who you want to be surrounded with, and they will likely be very prevalent at the tippy-top schools. Best of luck!
