Math-Bridge is based on an ITS and is an e-learning tool for mathematics that can be used in various pedagogical scenarios: acquiring knew mathematical knowledge, revising known concepts, deepening knowledge or training competencies. We carried out an experiment testing Math-Bridge in a short revision session with 96 first-year students before their mathematics exam. In the experiment we proposed a limited content concerning binary operations and groups to work on autonomously as a revision session for the exam. Students filled out a questionnaire concerning usability and accessibility of Math-Bridge at the end of the session.
