The “pro” argument is that at least last year the outcomes seemed pretty random. Lots of kids who should have gotten 5’s got 3’s, but also lots of kids who probably would have gotten a 3 in a normal year got a 5. So who knows, you may get lucky.
The “con” argument is bigger. First, I don’t think schools care as much as some people think even in a normal year about AP. If you have them, it’s a plus, but I don’t know that the absence is a big negative. Especially for the next couple of years until the kids currently in HS who took classes and tests during the Covid era cycle out. Everyone knows that lots of kids have negative things going on, and for all they know the teachers announced if you want to take AP tests you are on your own because we aren’t teaching that material in the class this year. My kids have had that happen during normal years.
The second thing I can speak to a bit is the block schedule. We have this at our LPS. It is less abreviated than what you have now it sounds like, but our classes are always one semester long, so end either in December or late May. So either you are 5 months removed from the material, or you still have a few weeks to go, which would be more like 6-8 weeks worth of material if it was being covered at an annual pace not a semi-annual one.
Our kids tend to not take the tests. Most of these classes are also offered for dual credit, so that option is much more popular The ones who do take the tests tend to be the very top students who plan on applying out of state (not that many students). They also do poorly, even though they are our top students.
FWIW, the most likely outcome is probably he spends time studying for the tests, time that would be better spend doing anything else, including decompressing and watching Netflix in my opinion. And he gets scores he doesn’t want to report anyway.
I guess the exception to that advice would depend on where he may end up going to school, as I know you are looking at golf so not necessarily just top academic schools. If he may end up at a school where he would get credit for a 3, then it may be worthwhile. You wouldn’t necessarily report that on your application, but he may be able to knock a few classes out of the way, which would also give him a lighter academic load in college, which is really helpful for athletes especially.
