The non-calculator paper can be tricky. But, because its a non calculator paper the kind of questions they ask you have to have simple maths involved. What I mean by simple maths is that the numbers they choose usually divide easily or convert easily. I've put together a list of maths facts, which, if you memorise, you will find the paper much easier and also be a lot faster at working things out. 1. The first 6 multiples of 15: 15, 30, 45, 60, 75, 90 Multiples of 15 and division by 15 is commonly used. Memorise the multiples and factors of each number that I've listed above. E.g 90/15 is 6 and so on. 2. The first 10 square numbers (more if possible): 1, 2, 4, 9, 16, 25, 36, 49, 64, 81, 100 3. The first 10 cube numbers (more if possible): 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000 4. Common fractions/decimals/percentages: 5. The times tables from 1 to 12. 6. Common Trig Values: I'll keep this updated if I think of any more - feel free to make suggestions!
