An exam question from C4 January 2008 involving modelling with differential equations. What do you think of this question? ❤️ ❤️ ❤️ Support the channel ❤️ ❤️ ❤️ / @mathonify
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.
@@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.
@@ForgedPlanetTV Yes, some exam boards have different specs and harder questions than others but then grade boundaries make up for that difference which havw always been throughly standardised
@@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
