Once you've set up on Classmarker, click on the TESTS icon on the upper right. Then, click on "NEW TEST +".
Create a name for your test and then click on "Start Adding Questions". You'll be able to choose from a variety of question types, like multiple choice, True / False, matching and short answer. NOTE: to make your test self-marking, choose question types that do NOT require any open ended answers. Multiple Choice is the best type for this.
Once created, your questions will form a Question Bank that you can use again for other quizzes or tests.
Your tests will be stored on Classmarker and accessible through Guides using the "Add Test" tool...
