AQA A Level Maths Discussion Thread - 2018 Edition

Hey guys, I thought I'd make this niiiiiice and early so we can all share how we're preparing for our Maths exams this year?

Statistics 3
Date: Monday 25th June 2018
Time: Morning
Duration: 1 hour 30 minutes
Days to go?: 49

Probably the most important way to prepare for maths is to do plenty of past papers! You can find the more recent papers here and the older ones here.

Also, Physics & Maths Tutor has some good resources for revision - everything from revision notes to questions on specific topics. You can find the Statistics 3 materials here.

Good luck with the preparations everyone, let the countdown commence! Image

Also for question 1 the critical value for r (PMCC) was 0.4973 so H0 was accepted I think.

Yeah each part of question 6 was only 3 marks, so provided it was just that part that went wrong then worst case 3 marks lost. Don’t worry about it 62 is still very good.
