Stick(sorry to involve you) did well in his year 11 class tests...for all we know, they could have been extremely easy. I don't think he has the experience or credentials to run tuition classes. Moreover, i think charging money for helping your peers (in this case, those in the same year as you) wrong. If i were a parent of a child who wanted to pay money to be taught by someone his own age, i wouldn't be too keen for that to happen. Tutoring requires a lot more than merely transferring knowledge and this comes with experience and maturity(not that you aren't mature stick) but you will find you grow a lot as a person throughout year 12.
You sir are a dick!!!
I personally tutored people for methods for methods and I received only positive responses, being in the same place as your students helps alot to understand the problems, especially when it is a weaker students. Of course I wasn't able to make 40+ students out of them, but they had their goals, which they achieved through my help, with their teachers commenting on their improvement. This is not supposed to be a self-endorsement, but rather an example that students, who aren't past vce-students have the potential to be really good tutors and especially for tutoring weaker students this shouldn't be a problem anyways.
And to remind you again he is only teaching what is for him the past in the same way as normal tutors do.
Stick already got a perfect score in further, which doesn't always mean that he is an amazing mathematician, but it certainly proofs that he knows how to study and I'm pretty sure he will give those tips along the way as well.
Anyways, Stick you're pro and just because some people, which this awesome possiblity isn't even there for, say you shouldn't do it, just don't care. I mean there are at least double the amount of people supporting your amiable effort. Just say to yourself some hipster slogan like 'YOLO' or 'Haters gonna hate' and help the 'cult' "Class of 2013".
P.S. It should be 'YODO' since you live everyday, but only die once.
