QA-Coach is a question-answer training assistant; it prompts questions selected from a database using a scientific method for optimal memorization of the answers. You can use it to learn vocabulary of a foreign language, mathematical facts and any possible matter presented in form of questions and answers. It stores in a database your performance on each single question and you will be asked questions in the optimal sequence determined by the program based on what happened in the previous tests. You can create and edit your questions and answers using the relevant program functions or import/export them from/to an external text file. QA-Coach uses Microsoft Access 2000 databases to store questions, answers and test results; however, you do not need to have Access 2000 installed in your computer. QA-Coach helps you to learn and remember expressions and notions through the use of an innovative time-based technology. Better than a human coach, the system asks you the right questions at the right time, and remembers your learning performance on each single question, over multiple training sessions.Interacting with QA-Coach is very simple as the system takes most of the decisions necessary to drive the training process. Your usage of the keyboard or mouse is minimized, and you can concentrate on the information to be learned, without having to select the questions to work with, which is done automatically, based on what happened in the current and previous training sessions.
