Hi, I recently did a maths mock, and I got 50/100. The thing is I didn't revise but I have a feeling even if I did revise, I probably would've got like 5 more marks. What I want to know is, if I revise thoroughly within this week (exam is next Tuesday), will I be able to achieve 100/100 so I can tell my maths teacher to STFU! Also, the exam board is pixl (Edexcel for the real one) - which one is the hardest/easiest? Thanks!!
