Analysis variance

I go through all of the rules in my free lectures, explaining them (with examples) in the way I find them easiest to remember. Other than that you can only really learn them y practicing lots of examples from your Revision Kit. However do make sure that you understand the logic behind all the rules (which, again, I explain in my free lectures). Not only does this make them easier to remember, but also only 50% of the exam involves calculations - the rest of the exam is testing that you understand, and simply learning rules is not understanding. The lectures are a complete free course for Paper PM and cover everything needed to be able to pass the exam well.
