Pacific Software Publishing, Inc, released "World Math Challenge Volume 1" on September 15, 1995. It took more than 6 months to translate and develop the Japanese junior high-school entry math exam into English. After 7 years of distribution, we finally stopped the production of this software in 2003. Instead of just making this software disappear, we have decided to make it available for free using the Internet. The zipped file you can download from this site is the demo copy of "World Math Challenge Volume 1." We hope you enjoy it. Thank you for supporting Pacific Software Publishing and Japanese-Online.com.

	The story problems provided in the software "World Math Challenge Volume 1" are translated from Japan's Junior High School math placement test. This test is given to 12 year olds and each section of the full test consists of 225 story problems. Students are given a time limit for each problem ranging from 1 to 5 minutes. If completed within the time provided, the 225 story problems require over 8 hours to complete. The problems are logic-based and consist of about 20 different types of story problems. The point of this site is to begin providing quality math content based on Japanese (maybe a world) standards. The Japanese continue to place among the top 3 countries world-wide in terms of their students' math abilities. The US was recently ranked #14 in international math placement among the industrial nations. We think that US students should be exposed to international level math content and this site may represents the first step.
