This is irrelevant to the thread but wrt HSC Physics - I agree that they should bring back more calculations and calculus based physics rather than 6-8 mark assess questions. As someone said all those questions about assessing or discussing impact of ___ on scientific thinking, processes, environment, society could be covered in a HSC History and Philosophy of Science course that would just basically be a rote learn course. The main reason why they took out all of the 'nitty gritty maths' was because they were afraid of discrimination against non-maths people. I think it is a good idea to have a cirriculum that doesn't have co-requisites so that no one is discriminated against but Physics is definitely a separate case. The reality is that Physics requires good mathematical skills - whether you like it or not. I think the Board, in trying to be 'equal and fair' have sheltered HSC students so many of them get a shock in uni (from what I've heard - and this is geared toward those who were non-maths people - but why would you chose physics in uni if you were non-math? lol anyway).
Back to the subject of 'skill building'... I think the main question to be asked is: What skills do YOU (as a student) want to develop? If people like Sy only want to develop logical thinking ability, making logical arguments, then of course such subjects are good for those skills. If you want to test your time management and develop those skills you might want to do English Extension 2, coupled with Society and Culture and topping it off with Textiles and Design. If you want to develop communication skills you may want to choose Drama. AND THE LIST GOES ON. You cannot just say that the ultimate goal of the HSC is developing logical thinking ability (that's what your post came across as Sy, I do not mean offence to you) - because it's not. It's about giving the chance for students to pick what they want to do and develop the skills they want to. All courses are skill building, in whatever form and we must respect that. Ranking them in order according to criteria is meaningless. Maths Ext1/2 does not develop your social skills, nor does it develop the ability to manage major projects that have deadlines (like in the real world!!) - for example.
Please think of the HSC holistically.
