Students

This site provides infinite practice questions, an online searchable textbook, and video lectures for students using Excel or calculators. We automatically adjust the difficulty level to your ability. Unlike paper textbooks, we do not offer harder questions until you can answer the easy questions correctly. The course is self-paced. You can proceed through topics as quickly as you want. You can stay challenged. You do not have to fear statistics. You can have fun and do well using these materials. We have a High Score if you like to compete. If you want privacy, you can keep your results private by using a secret alias name for the High Score.

Your success is important to us. We have invested over 5,000 hours developing this web site to help students succeed in a difficult subject.

We price our product to give you outstanding value. Your small payment will help us continue to support, improve and expand this product while keeping the price of education materials within reach of most students.

Teachers

We can help you help your students. We provide PowerPoint Slides for all topics. Our practice questions are generated uniquely for each student and graded automatically. We include a test generator. You select the topics in line with course learning outcomes, level of difficulty, and how many questions you want, and the test generator creates a test and the answers in seconds. You can cut and paste the test generator questions to a Word document, alter the text, but use the data and answers to save time.

We provide professors with a dashboard that shows class progress by topic, or individual student progress. Results are almost instantaneous, enabling you to see how a class or student is doing, and focus on the challenging areas.
