Excellent advice from all!
Work backwards. Rising senior summer you want to clear your plate and reserve for SLE, NASS, USAFA SS, Boy's State and AIM. That summer you'll do final prep for the CFA and take it the earliest window, then transfer it to the other SAs. 4/6 measures are more just pure hard work; the other 2 are more skilll based (bball and shuttle run). From now to summer rising junior year, plan to peak for SAT/ACT, and then piggyback that preparation for a stellar PSAT. Then you'll have your anchoring scores, and use them in the summer program applications. Can't emphasize enough to get the SAT/ACT anchoring scores done by beginning of junior year; frees you up to focus on other things.
Good to engage with clubs, leadership, and sports. However, be aware of which ones are more like gratuitous check-the-box activities, and which ones have significant engagement, can you tell a story that leads to defined/quantified achievement/leadership?
Any time now, also go over the Dodmerb form and address anything you were diagnosed with, or surgeries/hositalization. It's also a good time to preplan/address things like dermatologist visit and wisdom teeth, perhaps other things as well. My DD just had her wisdom teeth out at USAFA. She hit the genetic lottery and only had 2 uppers. But it was a 4 year wait, and lucky she had no pain although they were impacted her doolie year. If I could go back in time, I probably would have paid to have them taken out rising high school junior year, but it worked out really well.
You are on a great trajectory, keep it up!
