The SAT actually seems easier to keep somewhat level during this time to me, as long as admissions counselors have some recognition of the drawbacks.
I also wonder about the distinction between "not required" versus "not considered". It becomes a weird mental game if submission is still considered just not required.
What difficulty is there? As they've announced it's removed due to events this year, I honestly can't guess.
On B, I said it skews more towards the rich this year. Most years everyone at least has their school day.
If it is not required, it just becomes extracurricular. If it's not considered it's useless.
Something that is not required but still considered is beyond the curriculum, or extracurricular. Many colleges have allowed you to submit both the SAT and ACT, admissions uses all the data available and the student should present themselves as best they truthfully can.
I don't know why everyone else seems to be talking long term reasons, but both options seem pretty bad.
