Formulae
Every Edexcel Maths exam comes with the Mathematical Formulae and Statistical Tablesbooklet — but the specification’s Appendix 1 lists the formulae that are deliberately NOT in it. Knowing which is which saves marks and revision time. Here is the split, topic by topic, in our own words; the authoritative sources are the booklet and specification themselves at qualifications.pearson.com. Topics with no entry simply have no formulae worth flagging either way.
