3000 Secrets to Master Elementary and Intermediate Average Problems on the SAT and GMAT

Contrary to popular belief, the quant section of a standardized test such as the SAT, the GRE, or the GMAT does not really require the knowledge of much higher level mathematics. What is needed, however, is a strong understanding of the fundamentals of arithmetic and everyday math skills, many of which would initially have been introduced when you were in middle school or in high school! All you need to do to open the doors to the most important higher education destinations in the world is to reinforce the mathematical concrete of your crucial conceptual foundations.
The average of a set of numbers seems like the kind of concept that takes only a few seconds to master. After all, addition and division are arithmetic operations that are usually mastered in primary school. However, the complexity of applications of these operations in a quantitative examination quickly stacks up till it is easy to make a small error that will reduce your overall score.
The thousands of exercises in this book are in many different formats. They can either be used as timed exercises or to learn (since solutions are available). If you want to use them as timed exercises to simulate the experience of the SAT or GMAT, it is recommended to start 5 seconds above your target time per question, and then reduce the target time by a single second after every set of 10 or 50 questions, depending on how well you are doing; it is usually time to give yourself a harder time challenge once you are able to get 80% of the questions correct.
This book has been carefully structured to allow you to start off anywhere: if you already have a good concept base in the subject, you can start at a later stage, so that you can challenge yourself.
If you correctly solve 70% of the problems in this book, this will mean that you are an expert on any question on averages that the test throws at you; you will be completely prepared for more than a tenth of the all-important quant section.
