Poor. It takes an item, gives you the glossary description, then asks you to choose between the correct answer and one item selected at random from the glossary. The problem is that the glossary description often contains the answer. For example: "The Quality Register is used by the project manager and project assurance. What is it?" and the options are "Quality Register" and "Outcome". Very poorly thought through app.
Useful Clean and simple UI, no issues so far.
