Year 12 mocks went badly

one thing my teachers have tried to make clear to us with exams and predicted grades is they'll always give us the best possible prediction!! not in a like, impossible to achieve way, but if you've been doing consistently well in lessons and you have a couple bad days on mock exams they should still base your prediction on how you've been doing overall. i know it can be stressful but i would recommend talking to your teachers, so that they know you're worried about it. your average results are really good, particularly in maths! i'd say between now and a levels make sure you're finding revision tactics that work best for you, but your teachers should take your work over the year into account.

So it doesn’t matter, although you’ve clearly taken it as a ‘wake up’. 👍
Talk to the teacher, it suggest going in with:
That result didn’t meet what I was aiming for therefore:
What went wrong?
What should I personally be doing to get on?
Is there any extra assistance that you/the school runs?
I intend to get grade ‘X’ come what may..
Think of it from the teachers perspective, that’s absolute manna from heaven to hear from a student and I’m sure he/she will spend some time to get a well motivated student onwards.
Without knowing the circumstances as a starter perhaps just reflect on what exam preparation you did. What material did you review and crucially how much did you do in the line of practise exams.
Generally, even if you’re doing well, practise exams will help protect you from those unexpected and therefore difficult on the day problems. Without significant exam practise you can be vulnerable there to the variations in real world exams.
In no way worry though, you’ve got a full year and fundamentally you’re clearly in a great place. Obviously some changes to be identified with the teacher just. They’ll be very receptive.
