Questions

What was the grade C boundary for OCR A-level Chemistry in November 2021?
In November 2021, Chemistry: 107 out of 270; Chemistry: 69 out of 140; Chemistry (Salters): 94 out of 270.
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.
