Revision Assistant is an application that lets you define your own set of questions and answers. It will then randomly select a question, and you must provide the correct answer. You can also practice in reverse, by deducing the question from a given answer.

Here's how it works:

1. Create a new dictionary to define your terms.
2. A question will be shown. Try to answer it. If you are correct, mark it and move on to the next one.
3. You can also try the inverse: deduce the question from a given answer.
4. Complete all the questions.

Additionally, the application lets you define multiple dictionaries and saves your progress automatically.
