    MX1 - 2020 Syllabus - changes + additions

    The majority of the statistics topics actually sit in the 2u course. The statistics in 3u is largely just applying the 2u concepts to the binomial distribution (which has a nice link to binomial theorem).

    MX1 - 2020 Syllabus - changes + additions

    The new syllabus leans more heavily in the "applied" maths topics, often at the expense of more "pure" maths topics. So naturally, all the pure maths supporters would not be happy with this. Whilst it's not perfect in its design, I think the topic selection is now such that it better equips...

    How much does studying actually impact on your results?

    It's not that simple in reality. There are other variables involved. It's not a case of study vs no study has an X% difference. You have to take into account other variables like intensity and efficiency of study, how quickly the student understands things in class or during study, the...

    How much does studying actually impact on your results?

    A key variable to consider is whether you understood the content from the day it is learnt or defer understanding it to the day you study. This is particularly relevant for uni where the pace of learning is much faster than high school. If you already understood a concept in depth at the time...

    Use of 4U techniques in Extension 1 Paper

    The questions will typically be designed such that 4u methods won't be needed to answer the question anyway (at least not needed to answer it more efficiently).

    Boolean algebra

    I think the new syllabus will cover Bernoulli random variables when you do probability and statistics (then extending that to Binomial distributions). That's as close as you'll get to it.

    Multiple choice- first or last?

    When I did the 3u paper, I completed the last question first and then proceeded in normal order. Worked pretty well as I was forced to not squander too much time on the easier questions and at the same time get a decent attempt at a harder question, without the time pressure that comes with...

    2015 BOS Trial Q14b - Conics Parameters

    P is not a general point on the hyperbola. It is a special point on the hyperbola with those particular coordinates (you could almost say it is a point of intersection of an ellipse and hyperbola with the same values of a and b - but the ellipse is not drawn out).
