Vocab Builder is a collection of two separate programs. The client is the testing application that uses a drill-style method of building your vocabulary in a foreign language, similar to using flash-cards. The editor allows you to create a new, or modify an existing, database for your own personal use. Since the design of the project allows a user to create their own databases/tests, they can not only focus on the words they want/need to learn, but also are not restricted by availability of choice. No more are you restricted by only the databases available to you. Many language teaching applications only allow you to learn the languages they've supplied you. Most North American-based programs cater to English speaking users and only give you a selection of other languages to choose from. Not only can Vocab Builder use any language combination of Native and Secondary languages but it's also open-ended. You can share your tests with others. You can expand the database of words in any direction you want. Word lists are meant to be broken down into categories like colors, sizes, numbers, etc.

garith is a game similar in spirit to BSD's "arithmetic" or TuxMath. The game asks you to perform a simple arithmetic operation within a certain time frame. It improves your skills by stressing the operations you get more frequently wrong or that longer to answer. The statistics are saved/restored across games, so that each game is tuned for your current arithmetic abilities.
