I think that I may eventually get under-predicted as the mock boundaries in my school are too high. They should make it lower especially for the top grades. It is very hard to get a top grade in the mocks at school.
Chemistry A2 (4,5), Physics A2 (4,5):
A* 81, A 72, B 63, C 54, D 45, E 36. The Chem A* boundary is higher than all of the exam series since 2010 (highest was 80), and the A boundary is above both U4 new syllabus exams. The Jan 2021 one is also expected to be in the mid-60s maximum. And for Physics, if you get a B in my school, you will get an A* externally. You will get 120 UMS externally if you get an A. It just made A and A* impossible to get. How can you get above 80 in a new spec Physics paper? Only true geniuses can do that!
Unit 6: A* 45, A 40, B 35, C 30, D 25, E 20
45/50 for A* is insane. This is already enough for 60 UMS every time. And 40 for A is above all exam series bar Jan 2013. 37 will be much better.
And for Physics, sometimes even a C in the mock can be an A externally. This is insane.
For Maths, we have A* 68, A 60, B 52, C 44, D 38, E 30. This looks reasonable, but it should be a bit lower as well, such as an A moved down to 56.
