answering the second question, I think less is better because the teacher can give you individual attention and the small group of people tend to achieve a better average HSC mark than a large group.
Same here Affinity... Last year we only had one person doing 4u maths, and this year we have 11 people. What a jump... I think that might actually be a school record . But then again, it wasnt because that people in our school was good at maths, but it was because the standards had fallen...
to see the average class size, we can divide the results by respective "class size" that a person votes. But im pretty curious how big 4unit class feels like?
not so bad because if you do badly, theres always like 20 people who did worse. only problem is that heaps of people have questions to ask the teacher and you can wait a whole period to get some help.
Doing maths questions is very rewarding. It can be even better by keeping a maths skill level log, which increases everytime you finish a question :
[ Maths Level Log ]
{levels are independent of basic potential sum}
{levels are sum of experiences}
[ overal level : 32 ]
[ 4U HSC raw mark estimate : 70% ]
[ 3U HSC raw mark estimate : 82% ]
