Learning your class to get ready for raiding

When you start raiding you will come across players who will have seemingly good gear, gems, enchants, etc but are still bad players. The reason why is because of a fundamental lack of knowing there class mechanics, the raids in Cataclysm are much more demanding then during wrath especially since everyone at the moment is undergeared so getting the all out of your dps and heals is a must. Going to check some of the forums on Elitist Jerks or others will help make the difference.
