well in my experience all saturday classes were excellent, especially english and science. A lot was covered and you always remained weeks ahead of class. IMO english should be fine but mathematics could be a pain as you are just given questions to answer and not too much to debate or think about. Also since it is a class atmosphere, you can't really ask teachers questions, i am sure that pre uni still offers 1 to 1 and i found this great, I always spent an additional 30mins with 1 to 1 to revise on math i had gotten wrong. So whether it is english adv or ex1 go to 1 to 1 for sure to mark essays and get feedback. My favorite english teacher at pre uni is Mrs White, tall skinny mid 60s, maroon hair. She is great, excellent teacher and knows everything about all texts and novels. If she teaches, chances of scoring a high score in english will be much higher. also ask for the email of the teacher and send them essays or creatives once a fortnight if they are ok with it. What else u studying at Pre uni? Its at Macdonald college right?
