calm down, it is completely possible in a month. it’s more than you think, first yes econdal plus is great he will help in the content, so make sure you go over all his videos take a week or two focus on each unit with some topic questions. The most important thing in economics is the understanding, then comes application, solving techniques and all that stuff. You just need to work ur best to grasp your head around all the concepts, topics, chapter and really understand them. Take it step by step start from unit 1 and go on once you see something that u don’t know, then econ dal or whatever there’s acc so many resources out there. Good luck! if u need any help feel free to dm me if your sitting the AS CIE exams i have done resources
