From looking at the specimens, The breadth has 20 Multiple choice which I believe is the hardest. The rest is, if you know your physics you can apply knowledge quite easily. However the depth is another story.... There are like 3-4 6 markers JUST on experiments, therefore I recommend you memorise every experiment, you can pick up easy marks there. Good luck everyone, PM me if you wanna discuss more on Physics, Maths(Edexcel) Computer Science (AQA) or Economics B (Edexcel)
