Hi there. As it said when you registered here but possibly you missed it -this is not your school Moodle but the main Moodle site where people talk about and download Moodle - you will need to go back to your Professor and ask him the exact web address of your moodle so you can log in and get to the quiz. It's possible if you could give more details about where you are studying that we could help you find it on the web but even then we wouldn't know what your login details were
