It contains some item sets but they’re very poor. For example, some of their item sets have a full page of texts, then 6 questions that you can legitimately answer without having to read the actual vignette. They might as well be stand alone questions.
I thought the schemer question bank didn’t contain any item sets and rather was made up of individual Level 1 style questions. That’s why it’s not as good for L2 as it was for L1
