do teachers choose the modules we do? how does it work

The school usually does. My school chose the matrices and network modules for our SACs. On the exam, you have the choice of any 2 module you want to complete. Very few people chose the modules not taught in class at my school because usually that won't end well. Note that from next year onwards, FM (renamed to general maths 3/4) will no longer have modules, the matrices and network modules will be made compulsory in unit 3/4, along with the existing stats + financial core modules

Oh really, so next year their no choice. Thank you for letting me know. Where do you find out about these changes

    Hi, I'm having trouble with Q6 in the Networks module in Sample Exam 1 2016 (VCAA). Could someone tell me how to do it faster? Because trying to figure out if a graph is planar is SO time-consuming by re-drawing!!! Thanks in advance 🙂

    Hey Bioho4,

    It is a very time consuming question.
    Usually when verifying if something is planar, I use the euler's formula, v-e+f=2.
    However the problem with this shortcut is that to tell the number of faces, it needs to be re-drawn with no edges overlapping, which obviously makes the shortcut a mute point.

    In practise exams, I never really draw them out. I visualise in my head how to make it planar. This is much easier for the last two in this question, but it is just going through combinations of how you could re-arrange the edges to not overlap.

    While it is difficult in your head or on paper, I have found it gets much easier with time and practise. Usually exam 1's will not be very time-stressful anyway, and I haven't come across any exam 2 type questions of these sorts.

    Maybe someone else has a much better method, but I haven't come across it in over 30+ further exams so far.
    If they do, I'll be keen to know it.

    Hello,

    I am just wondering what VCAA thinks about multiple modes.
    I came across a non-vcaa prac exam question where there were 3 modal values.
    Eg. 1, 1, 2, 3, 4, 5, 5, 6, 7, 8, 9, 10 ,11, 11, 12
    Then it asked me what the mode was. I chose the option C., which had 1, 5 & 11.
    The correct answer said there was no modal value.
    Is this what vcaa thinks?

    Is Bimodal the maxiumum in terms of VCAA, or would they accept trimodal+ answers.

      Will so sorry about the late reply, but if there are more than two modes then you don't talk about the mode. I doubt VCAA would ask something like that question in MC, but for short answer just stick to 1 or 2 modes, and no more!
