Re: 2012 HSC MX2 Marathon Ah, I see, thanks.

Re: 2012 HSC MX2 Marathon Would you mind going over the second example? Didn't really understand the method.

Re: 2012 HSC MX2 Marathon Could this be done geometrically?

Just to add to bloodvial, integrating with limits saves ALOT of working (no need to find C). Just depends on the question.

This question makes me sad, does it involve multiple congruent triangle proofs?

99.95 - nope, >99.5, yes

Would the required raw mark for 3u/4u also inflate in the same way?

I always thought that the band 6 minimum was set based on the test itself - irrespective of how the state performed, meaning if everyone fit into the band 6 criteria, everyone would get a band 6. I could be wrong though.

Does that mean for a band 6, we will need to meet both standard and advanced outcomes? Or are they overlapped?

Even though the Hsc marks --> Scaled marks is generally down, it really depends on how much it scales down. For example, say you have 10 units, 90 hsc mark in each subject. If each subject scales down to 80 (just an example), your overall ATAR would've been ~94.5 last year.

Wish I was doing english advanced instead of standard. And not doing SOR 1.

I think nasals.

It shows you need to do well in standard to get decent scaled marks. I'm still unsure if it's the aligning or the candidature that plays the bigger role (the standard cohort wont be that strong). Guess I'll find out this year.

How the physics cohort goes in english compared to how they go in physics.

Yeah, but first place always gets the highest mark regardless.

I drew the experiment and made reference to the boat analogy, using two constants I labelled the average speeds. Perpendicular to the aether I labelled as c-w, and parallel I labelled as c-z, where z>w.

Are you talking about ax + by + c - k(a_2 *x+b_2 *y + c_2)??

Ah, thanks. Yeah, I know it's broad but I want to start working with them early, was completely stumped once I got to Q6 in the CSSA paper (only can get like 4/15).

Hey, would anyone have a list (or rough idea) of the proofs that can be asked in Q6? Particularly those that seem to reappear in the HSC, don't want to do what I did in the CSSA paper in the HSC itself. Even if there's a general method that most of them follow to prove. Thanks

Yeah, I think the 21 one was wrong because it didn't factor in the factor there were two R's, therefore the would be less combinations (I think).
