I see what you’re saying mums, but teacher predictions are always on the optimistic side. It happens every year that students don’t get the grades they were predicted. Also, unis significantly over-offer every year, in the knowledge that a good proportion won’t get the grades. Having 2 years work, 100% assessed on a single exam isn’t a perfect system either.
As Monkey says, the results this year will be probably the best ever. As always, there will be some anomalies, but even then, chances are unis will use their discretion and be flexible (particularly in the cases if those in low- performing schools). Plus, there are the Autumn exams anyway which is a “second chance” for this years students that has never happened before.
If there is an “outlier” student in a very low performing school, presumably they would have also done well at GCSE. These students exist in every school up and down the country and I’m sure the last thing the Dof E would want to do is penalise an “outlier” student. It should be obvious that if teachers in a school are generally predicting Cs and DS, but suddenly there’s one in the cohort who is predicted As, there will be reasons for this. They can look at GCSE results as evidence of the trajectory of outliers if they need to?
