I have one major annoyance when it comes to this program, everything assumes UK pronunciation. Even for the supposedly US version. I sit at my computer repeating words over and over again in my natural native speech and get things wrong, then say it in a semblance of what I believe an English accent would sound like and then I can hear it and get the answer right. Also the small word limit on written assignments is detrimental. I have to cut back my explanations so much that I can't even fully convey what I am trying to make clear. I cut back too much and fail an assignment because I reportedly did not hit all of the target things, when I literally paraphrased one of your own activities in a video to the short word limit and just changed the topic. This is quite frustrating trying to find the balance of brevity but specific enough to get all of the targets with only 100 characters. The grading is also fairly subjective without a very well-defined rubric, one of my feedback responses even told me I needed to put in all of the things that I did put in but said I appear to assume things, like they aren't even sure what they are grading. They said I should use visuals, and I described using pictures. They said I should drilling for pronunciation, I specified exactly that by having the class repeat back as I speak. They said I should write form, I explicitly said I wrote form on the board with examples. I was still marked wrong. Feedback was unhelpful and subjective. I have already had to buy one extension because of life reasons and these annoyances just make it all worse, and now I might have to buy another one and I am asking myself is it even worth it when things are given in such an unclear manner.
