Hardest to easiest:
Psychology AQA - At AS it was the easiest but I couldn't keep up with it at A2 because you have to remember so much more which I cant do. predicting my grade to drop to a C (optimistic) from A
Maths C4 Edexcel - tbh I think maths is easy to pass if you just churn through past papers but c4 will be the hardest, If they make one question horrible an I mess up then thats my grade gone.
Maths M1 Edexcel - ..
Maths C3 Edexcel - ..
Product Design - Edexcel - failed the AS exam because I didn't revise (no resources online and hated making notes) but now I realise how easy this course is I should get an A
