If you look at the marks needed for different grades in chemistry 9701 component 12+22+23 in different years, you will see that the marks were highest in 2018 and lowest in 2022. This means that the papers were easier in 2018 and harder in 2022 (or may be effect on students after covid-19).

The difference between the grade thresholds for A and B ranged from 13 marks in 2022 to 16 marks in 2018. This indicates that the gap between the top performers and the second-best performers was relatively large and changed significantly over the years.

The difference between the grade thresholds for B and C or C and D were relatively small and changed moderately over the years.
