    BoS trials Maths and Chemistry 2020

    Thanks for the very detailed response! From all the students here we all really appreciate mods and past students pitching in to help. I suppose maybe extrapolation in this case is "acceptable" in the scope of the HSC, but not so for further studies. But I agree that its likely that NESA would...

    Yeah, true. Honestly it was a good difficulty. You wouldn't be able to do very well at all without knowing your stuff well.

    There was an equilibrium calc which was whacky, a precipitation titration and an enthalpy calc but I can't remember the rest

    It was so different to what I've seen before. A lot of the questions seemed very hard at first but turned out to be easier with some problem solving and thought. But definitely harder than 2019 by a SIGNIFICANT margin

    Ok cool, thanks for the answers - things are never simple in real life are they haha Do you think marks would be deducted in HSC if I extrapolated to 0,0? Kinda confused if i should listen to my teacher or you folk

    I might be being a doofus but doesnt the anwers in your paper contradict what you just said? "The lamp in AAS contains the element to be analysed. In this case it contains strontium. The lamp therefore produces specific wavelengths of light that can only be absorbed by strontium ions in the...

    Response from my teacher: " Yes, it is always okay to include (0,0) as a point on that graph. It is reasonable to assume that there will be zero absorbance when there is zero concentration of the stuff that is absorbing the light. Just be careful if you are provided with axes that already...

    An example I have found is the 2019 PEM chem paper. I understand what you're saying and I trust you, but I know for sure my teacher has explicitly said that you are to add 0,0 as a point in your graph. He's been teaching far longer than any of us have been alive haha I might email him and see...

    Thanks! Hey whoever put together this paper: in the AAS graphing question you say you cant join the graph up to (0,0). My teacher says you MUST do this and will lose marks otherwise - other past papers agree. Not sure if you want to fix it or not since its a bit ambiguous.

    Yeah, I know. It's just I keep making dumb mistakes. I know most of my stuff but once i get past 1 past paper in a day i make stupid errors like this morning i did 2019 hsc first and got 91, but now I'm doing BOS and I'll probably get low 80s

    Imagine creating a chem trial so long my stapler couldnt staple the whole thing haha And wow this trial is making me feel dumb :(

    Idk I've seen it done differently in different places. I'd go with NESA for obvious reasons

    Any news on the chem solutions? The exam is creeping up haha
  15. M

    HSC Chemistry SOLUTIONS / Thoughts / Predictions

    Yeah we didnt do them either. Many exams include them, but walk you through them such that you do not need to actually know the methods beforehand. I don't think it's in NESA's interests to include these titrations as it is essentially luck whether students know the methods. This being said, I...
