@kheimann In order to create a cumulative vocabulary question like you are looking for, you can create the week one version of the question and add it to a bank (either Question or Item depending on if you are using classic or New Quizzes).  Then you can duplicate the question in the bank, and edit the duplicate version to add the additional terms.  By duplicating and editing the most recent version of the question each time, you will have a series of questions that accumulate terms.
