The unit is really good, I enjoyed it. I had a crappy lab demonstrator so be prepared because I couldn't ask questions since my lab demonstrator didn't clearly know how to explain things so it was more self-learning. The first lab was really full of calcs but the others are more chill. The tutorials are not compulsory attendance which is great, you can as questions and get the answers well explained. There are some prelabs for all labs but is like 5 easy questions. Also, there are some drop-in sessions if you want to ask Hendra any questions, he is really nice and explains things very well. Overall the content is very chill if you're good at memorising and with basic chemistry.
