Will the bell curve be determined for each individual prompt, or will all the prompts be lumped together for scoring?
We have no way to know at this time. I’d GUESS per-prompt, but definitely no clue.
Nobody knows right now how College Board is planning to give scores for exams this year!
We won’t know if there is any curve until after the exams have been submitted.
We won’t know until College Board tells us. Sorry!
