So I'm doing Edexcel AS -Level Maths (2017 SPECIFICATION) and plan to continue to A-Level maths for definite (by the grace of God). Currently I'm using my GCSE calculator Casio FX ~ 83GT PLUS, and i asked my teacher if we need a new one. He said we don't need a new one but I don't know if he means for just AS, because i meant for both years - both AS AND A-Level. People from my old school had to buy calculators but it could be because theyre doing a different course altogether (ocr mei), they have the Casio FX - 991EX . It's obviously better if i get the new calculator now as i could get more practice with it, but im not sure as to whether or not we might need it? (because isn't a- level maths supposed to be harder and thus require better equipment?)
i do the same spec and yeah you do need it, youll need it for stats cause we dont have the tables written in the exam paper anymore and the new calculator generates the tables for you.
The Casio classwiz is nice, even though the Casio FX ~ 83GT PLUS should be fine.
