Basic Concepts of Microeconomics

This book includes most of the basic contents covered in a microeconomics class. If you want a book that is concise and to the point, I suggest reading it. Although it is not one of the most exciting books ever, it will certainly aid you in getting better at economics if you are completely lost and do not know anything about it. I must warn you, though, that it is multilingual; some of the chapters are in English, some in Spanish, and some in French. Enjoy!
