Maths Skills in A level Biology

While I do appreciate the effort that has gone into this, and it could be a useful resource, there are so many errors with the answers, and even some of the examples and notes. While some of these may simply be typos (for example on the first page of the first booklet it says "1 centimetre = 100 millimetres") it hasn't saved me the time that I'd hoped, as there are also simple mathematical errors in the answers (e.g. "5.8-0.8 = 4.0"). Both of these combined led me to lose faith in the reliability of the resource and have to go through and correct/rewrite portions of it.

A really good idea, great to find resources to support this area of the specification especially as there are answer books! I wondered if you had a maths resource to cover 6.4 Graphs as this wasn't included in the bundle?
