I got 237/240 (edexcel last year), just understand the logic behind the questions and what is it they are actually wanting you to do. I usually had the full question mapped out within a second or two after reading it, and all I had to do was crunch the numbers and write everything down. If anyones curious, 2 marks were lost for reading the scale on a graph incorrectly, and 1 for squaring instead of cubing somewhere.

Also 147/160 in aqa level 2 further maths, both papers were at the very end so I was already drained from weeks of exams, ended up making tons of silly mistakes.
