Moodle is one of the most extended Learning Management Systems and is based on the open source (GPL) license agreement. We summarize the advantages of the use of this environment and show our six-year experience with the tools that Moodle provide. It would be of interest that any exhaustively used tool, such as quizzes, could reuse the knowledge that teachers store year after year in the Moodle database. In this work, a web-based tool allowing us to create, integrate, reuse and manipulate questions and quizzes is presented. KEYWORDS Moodle, integration of quizzes, tools.
