My DS just went through A-Day, here is my perspective.
First, Test Scores are just one part of the calculus. A high GPA isn't the end-all, be-all because schools vary greatly, teachers vary greatly, and classes and class options vary greatly. None of these data points in and of themselves provide the sliver bullet. They use all of these data to triangulate and come up with the most accurate view of the candidate as possible. All of these data allow them to construct a mosaic that tells them who the candidate is. It is not perfect. It does make mistakes, and the ambiguity of it all can be frustrating for those of us that navigate through it, particularly when our DS is try to optimize for it. So the test scores do matter.
As far as them being required, I am glad I do not have to deal with it this year like some of you do. I will say this, we had been told several things about BCT and the transition to AY that ended up changing. Some parents got their noses bent out of shape over it, but the fact is, USAFA is trying to figure this out too. There is no playbook for it and they are trying to do their best. One example, Their colleges sports Division (Mountain West), last week said they would postpone the season two weeks. 3 to 4 days later, they cancel for the entire season (or actually they technically postponed I think). What changed in those 3 to 4 days? Seems kind of silly to make a big announcement and then go back on it within 4 days - but that is the nature of this thing. Doolie Day Out, Parent's Weekend, Days in Jacks Valley and other dates - all subject to change.
So, you have to go with what you have been told, but be ready for that to change. I think the USNA forum is fond of the term Semper Gumby...I think that fits this time well. If whole states are shutting down testing, I don't know how USAFA can realistically require it. What I have seen of USAFA is they stay the course until they absolutely have to make a decision. We don't expect a decision on whether Thanksgiving break will even happen until October. So, I think they are staying the course until they are forced to do otherwise - maybe testing will open up again in late fall, maybe they push back decisions for testing in Jan - who knows how COVID plays out. I know this sucks for parents and applicants.
There is enough uncertainty for those in the process as it is without introducing another level to it. So I feel for those going through it. Try to keep your heads on straight, control what you can and adapt to what happens next. Semper Gumby.
