When creating your adaptive test you can pick which specific module you'd like to test from, or comprehensive, which comprises all of the modules in one test.
On average, each module will consist of around 30 questions. So the comprehensive EMT Module, Topic, Objective should have around 30*7=210 questions to answer before it finishes. This number can go down based on how you are doing on the test. So you may end up answering a lot of questions correctly and having considerably fewer questions total.
