I'm currently in year 13. I think if anything last years grades were inflated, which is what they're trying to reduce this year. The 1-1 meetings are probably just going to be them telling us our grade so they have less appeals to deal with, or to give any evidence to our teachers if we want to challenge our grade.
I think it's unfair in some ways, this year they have more time, but surely that's only going to make this years grades more accurate? If I got my predicted grades, that would be way higher than what I'm likely to get given by my teachers. Also last year you could've resit if you really wanted to, which is what they'd argue
Universities don't really look at your GCSEs anyway so I don't think it's that big of a deal.
