    Small correction! At 6:49 I start waffling on about calculator buttons and forgot to subtract £2500 from £2590.81 🤷🏼‍♂️ The answer is £90.81 - my bad! Don’t forget to check out the Ultimate Grade 6-9 Revision video here: kzread.info/dash/bejne/oW2K17yhc9S4Yrg.html

    No Sir unfortunately this is near impossible to do, one topic can stretch from grade 5-9 depending on the complexity and variety of topics involved, this video kzread.info/dash/bejne/oW2K17yhc9S4Yrg.html covers all the topics from grade 6-9 but to categorise them into one grade would be misleading as we can’t really classify some of them as being a ‘grade 7’ or ‘grade 8’ question, they are merely a collective that fall within a spectrum, we can certainly classify a ‘grade 8-9’ topic or style of question and I have done a grade 8-9 playlist to help with this! 😁🙏🏼

    I use a formula in all of these, I just don’t write out a formula as it takes away from the understanding, but you can use a formula if it’s something that you prefer 😁🙏🏼

  • @theredstonebuilder1120

    Here's another way of working out questions like at 14:37 (when working out the value of x%). You make a formula like this 8000 × ((100 + x) /100)^3 = 8589.93 That bracket part in the middle is to work out your multiplier, and the x is the actual percentage. Then you rearrange (divide by the investment). ((100 + x)/100)^3 = 1.07374..... Then cube root both sides. (100 + x) / 100 = 1.02399.... Then times by 100 100 + x = 102.399... Then subtract 100 from both sides. x = 2.399 which rounds to 2.4. So x = 2.4% Hope this helped, I find it an easier way. But use whatever you prefer 🙂
