Depends on which exam board, WJEC is significantly easier than all of the others yet somehow grade boundaries are similar. I think it's because on average people who take it are worse students.

All exam boards are made to be the same, because they are all standardised

@@adam6543 The content is mostly standardized but the difficulty varied organically due to differences in populations doing different exam boards. Just compare an Edexcel and WJEC paper with their timings and you can tell.

@@adam6543 But what I'm saying is despite grade boundaries adjusting for difficultly, some exam boards have worse students on average, lowering grade boundaries relative to difficulty
