I’ve started to prepare some materials on basic Economic concepts, which I hope students and people interested in Economics will enjoy reading/ watching. Here is a video on part 1 of demand, supply, and elasticity, which is about demand concepts. Those interested to have a broad overview of the Economic topics, and how they fall in together for the “A” level syllabus can go to: http://homeworkelves.strikingly.com/ for a copy on the overview. Enjoy learning!!
