We've done so much more in our booklets at school than is in the specification? For example, in Biology we've been taught how to use the 'Punnett squares' for inheritance in the Cell Division and Inheritance (2.7) topic, yet this isn't in the specification at all for 2014 onwards - does this mean constructing one/reading from one won't be in the exam? There is a lot more information in my booklets/notes at school than whats in the specification..so I'm not sure if its worth learning all of this or I really don't need to know it?
