Oh good 😂😂😂 sorry I just assumed everyone did stats and ignores the D1 etc 😂😂😂 I find stats easy tbh, if I could just continue with stats next year and leave the core behind I would but I don't think you can do that unfortunately 😂🙈 how do you find it? It's my last exam so I hope I will have energy left by then but I have half term to revise still 😊
Hahah, no that's absolutely fine- no need to apologise lol. 😂😂 Thats great! Yeah- most of stats is good!! Although I hate the fact that a small incorrection when inserting the numbers into the calculator can wreck everything bc its all v follow on..if that makes sense. For example in standard deviation stuff..otherwise it's straightforward. Yeah, I was debating as to whether I should do M1 next year but I think I'll be doing stats too.
Hahah!- yes me too, hopefully you will.

5. Does anyone know the difference between stationary points and turning points? Lol.

Also does anyone know what formulas we may need to know for optimisation questions such as 'volume of cuboid' etc...
