Hi. Unfortunately right now it is not possible to put all of the questions you got wrong into a quiz.
We are working on getting a new system out that will allow this feature but it is at least 1-2 months away so probably not so much help to you.
The only option I can think of is to open each question and try to solve it (the answer choice and explanation should not be visible when you do that). The downside of course is that you won't be able to score/grade yourself automatically or to save the results.
We are working on improving the tests, however, and if there is anything else that bugs you or you need, please do let me know.
Thank you!
Best Regards,
BB.
