For Eco, even if you know all the content it's still not enough for a good grade.To achieve the highest possible mark for eco is to learn how to master exam technique. For the 10 markers, make 10 points of analysis and apply to a real world situation and/or extract. 25 markers, an intro of definitions and key arguments. A for and against with supported evaluation throughout whilst applying info from extracts or real world examples providing it's appropriate. For multiple choice, it's just about practise. Normally you have 2 definitely wrong answers and then 2 either right. You just need to be confident in identifying what one is right. I thought eco is linear now? Therefore eco wouldn't really count?
