Schaum's Outline of Principles of Economics

I am an old beginner in Economics. I just wanted to study to prepare my CMA certificate. Schaum's series are very popular in Korea, and maybe in the United States also for their selected many problems. That's why I chose this book for my preparation in Economics exam. Economics is very broad and practical studies. This book is written in 1995, 5 years ago from now. Someone feels it is too old to study. But I don't think so, because how much change in 5 years in Economics. The economy of a society is changing a lot in 5 years evidently but the Economics cannot be changed a lot in 5 years even in these E-days! I graduated from school longtime ago, and sometimes I was stupid in my school days because I just studied the text only without so many problems. I am now sure that the problem-driven study is the best way to conquer the complex theory. Good luck to you, and hope to find this book to help your understanding the Economics theory and extend to your real life.
