Sounds like a solid skating strategy. Good for you!
Remember test dates are unpredictable and will be for the immediate future. Depending on when your college applications are due, get your senior tests ready and/or done as much as possible by September 2021 for two reasons - 1) you can put these on your college applications, and 2) peaking for testing will be harder in senior year because you will be so busy with school, college applications and the competitive season being back on (hopefully).
You might want to schedule testing your senior pattern dances after the 2021 NSDS finals in mid-September (if you qualify) so you don’t ruin your eligibility. So testing the rest of your senior/international dances in late September/early October frees up the rest of your senior year for school work/college applications/competitions.
It would probably be helpful to have solid essay drafts of your top school choices done during summer 2021.
(As for forums, you can skim Goldenskate and FSUniverse to see what’s up in the international skating world, but perhaps not posting. It gets a bit snarky, to put it mildly.)
