people saying 2019 grade boundaries will be similar to 2024 ones

Well I think the aim was to have boundaries back to pre-pandemic but last year some exams had grade boundaries higher than 2019, overall, you can't really tell because all exams are different and it depends on how everyone did as a whole, but grade boundaries tend not to fluctuate massively, saying that though, sometimes they have, there's really no knowing and the grade boundaries depend on the subject so asking a very generalised question about all the grade boundaries is difficult to answer.

to all the people saying that the 2019 grade boundaries will be similar to the 2024 ones is this true and if so how similar will they be?

they said the same thing for 2023 gcses
at this point you can never really know, they make grade boundaries based on the performance of the cohort as a whole so there isn't much point in trying to predict them

so they create grade boundaries based off of the highest grades and the lowest grades of all 2024 students taken the exam and everyone in between

I've heard that they aim for a percentage of the people who took GCSEs to get certain grades, for example (this is probably not what it is actually) but 5% should get a 9, so they'll see what the top 5% of scores are and ig they work their way down, that's what I've heard tho, idk for sure
