DD has been doing her research and is very interested in some courses she's look at requiring AAA, AAA-AAB. She's just sat exams in Year 12 and the initial forecast for predicted grades is A BB. Predictions will be reviewed in the summer, so she's going to work really hard and has asked to resit one exam.
Worst case scenario, she's forecast ABB. Is is worth applying to the unis that require AAA/AAB, especially as the A is relevant to what she'd want to study. I don't know what else they consider, at GCSE she got AAA in the subjects. Her school report is likely to say she's a quieter pupil in class, but takes a full part in school life contributing to it and already has one Upper Sixth role and is applying for another.
