Fill in what you already have and leave the rest blank. A blank box means not sat yet, which is not the same as a zero.

Questions

What was the grade C boundary for OCR A-level Chemistry in November 2020?
In November 2020, Chemistry: 110 out of 270; Chemistry: 73 out of 140; Chemistry (Salters): 100 out of 270; Chemistry (Salters): 54 out of 140.
Will the boundaries be the same next year?
No. Boards reset boundaries after every series so a grade means the same thing even when a paper is harder or easier than intended. Past boundaries tell you the likely range, not the answer.
