I have seen this throughout the curriculum and practice questions: Explaining why certain answer choices are wrong by saying "what is this even talking about this is clearly and obviously not right" and then providing no further explanation is not helpful, especially for questions which only 20% selected correctly... it would be more helpful to point out "red flag" key words or mismatched phrasing or content that doesn't match the actual passage or something instead of saying "this obviously has nothing to do with the passage." Some wrong answers do have to do with the passage, but there are key words or phrases that give it away as being a tangent or diverted point - that's not the same type of strategic thinking as "oh, this is obviously wrong this has nothing to do with anything" or "yeah this is obviously the right choice." I'd guess that most test takers, especially those who are learning test strategy, don't think like that while going through practice tests, and it is almost ridiculous to present that kind of thinking as effective test strategy.

I wish there was a pen function so I could write electronically directly on the stimulus/white space

#feedback I don't find it helpful to only show the right answer first, I think it would be more helpful in the lesson to take a look at all the answers, take a quick guess, and then dive into which one is right and which ones are wrong. It's too obvious why it's the right answer when it's already explained beforehand. On the test, the answers are laid out first, and then it becomes clear which one is correct, not the other way around.
