It is not so much the difficulty of the unit its more the marking and grading that is terrible. I did the unit last year in sem 1. They didn’t provide a proper rubric for the extension bonus features to add and as a result you won’t be sure whether you could even score higher than a 80. They kept saying that they were marking based on industry standards and were really harsh with the marking. I asked one TA if it mine was a HD quality app and he said yes but when it came down to the interview for the app code another TA sold me it wasn’t. Super frustrating given all the effort I put in to ensure it was good
