The Test Expander add-on is a tool initially designed for teachers to help them evaluate their students. Teachers create a unique test with several questions in a Google Forms file. They must have a spreadsheet containing the students’ information, including their email. The add-on takes the test created by the teacher as a template, the teacher is asked how many sections and questions per section wants to include in the test and then, new randomized tests are created (one for each student) using the set of questions that the teacher initially had in the test template. Each new test is sent by email to the correspondent student.
