Speaking of crappy teachers, my chem teacher is retarded...
During orientation / transition, he spent an entire period gratifying his lab coat and then he showed us his wedding video - because thats what teachers usually do during their introductory lesson ...
He refuses to tell us his name ( although we all know it) and goes by 'K'. He claims to be Chinese one day and Greek the next... He strings together the most random letters and tells us hes swearing in Mandarin...
Hes a short, bald bogan who kind of looks like Sanjay Dutt in Agneepath- that same creepy smile...
And his mood swings... Oh my, he is worse than a menopausal woman who is neglected by her husband and forgot to take her pills that morning ... During transition week he walked down the corridor with his graffitied lab coat and glasses like he was some chemistry gangster and stopped infront of a girl who was holding a box of chocolates- he grabbed it off her and licked, yes licked the entire box before asking if she wants it back..
So I feel your pain!! If I can survive 'K' you can survive anything .... As mentioned before VCE is all about the individual, and you said you have great tutors, so you'll be fine.... Ha, and to think this guy will be marking my SACs....
You honestly made me laugh. That was so funny, especially about Sanjay Dutt.

Ok. I, on the other hand was priveliged enough to have excellent teachers for year 12. Despite this, I have a tutor for eveny single subject to ENFORCE THE IDEAS that are being explained and to also provide me with extra materials (for sacs) that I would have no chance of getting as teachers hold on to them as it were candy....
Anyways. What I would do in your situation, Tisara (which btw is a really nice name...its....pretty:)) is I would study by myself in class, reading through notes, making notes, and finishing homework. I would still listen to the teacher, but with a relative amount of criticism in mind, as they are not the best teacher in the world. I wouldnt ignore them, ecause despite how weird they are, they are qualified, and they could always tell you some small miniscule amount of information that helps to connect the dots.
Everyone's is oviously very smart on my Spesh class (in my case...I beg to differ) but my teacher SPECIFICALLY TELLS US TO NOT LISTEN TO OUR TUTORS, so she goes through the course in a different order so it would make more sense, rather than going chapter 1, chapter 2, chapter 3....etc etc.
My point is, listen to your teacher, have an open mind, but always keep in mind, that they are not the best teachers.
Hope this helps:)
