Test Builder 123 can be used to create tests as well as take tests. Tests can be created with the app or supplied by the user in a .txt file and imported using iTunes. If a test has pictures they too must be imported into the app using iTunes. If a test is made with a .txt file the format must be as follows:

1. Question

There are 2 modes to take a test. One mode replicates a realtime test experience and submits the results to a provided email address. The other mode provides the user with immediate feedback with the correct answer and an explanation.

If sending exams by email it's best to send them as zip files as some email systems may add hidden characters and corrupt the .txt file.
