I think you are right about this. The AP online tests were a disaster given how many kids were unable to submit their work and had to re-take (and a handful were STILL not able to upload the second time either). Many schools are offering in-person SATs and PSATs, even when their instruction is all online. This gives them a good practice run for how the APs might look like in the spring.
Frankly, if they can be holding sports practice in person, even though instruction is online - as our high school is doing - they can find a way to administer APs in person. We know more about this virus than we did back in the spring of this year, which helps too.
