Suggestions: 1. There were a few spots where there was like an extra minute of pause time after the speaking and before the 'next lesson' button appeared. A bit random. Minorly frustrating. 2. There were a few quiz questions that were content that wasn't covered. 3. I took notes. It really helped. I wonder whether you could advise people to take notes, or pay extra to get the written version. I definitely would not have passed (i.e. got an 80%) without having taken notes. 4. Overall it was enjoyable and the right level of detail. Worth the money. Well done.
