    HI Yunhong, I messaged you privately a couple of weeks ago. Just checking that you got that message. Best wishes, EM

    Piano

    Music 1 is a bit disappointing in how poorly it scales. My son, a self taught musician, scored 96 in Music 1 but it scaled so poorly, it wasn’t included in his ATAR. Ah well, at least he enjoyed taking it as a subject. @Life’sHard, so what do you think of the dynamics of his latest arrangement...

    What Is The Latest You Can Switch A HSC Subject

    A lot of schools offer compacted programs for individual subjects in Yr 11, so there must be ways to cover preliminary & HSC content in the one year, but no way they can enrol a student a couple of months before the HSC.

    Epidemiological study

    Both cohort and case-control studies are observational studies. Cohort studies can be either prospective (as described by Masaken) or retrospective. In case-control studies, the demographic details of the controls are matched to the cases as closely as possible (age, gender, +/- ethnicity...

    What Is The Latest You Can Switch A HSC Subject

    I agree with you - I don’t think they can since the school has to submit assessment marks. The student wouldn’t have completed the tasks (assignments, tests, trials), so they would have to give them zero for all the assessments that they missed.

    Choosing schools for OC (opportunity class) test application - NSW

    I’m not trying to elicit identifying info, but is your child already at Beecroft Public? Beecroft Public ranked third overall in the last NAPLAN (https://www.smh.com.au/national/nsw/naplan-year-5-results-the-state-s-top-schools-revealed-20230222-p5cmls.html). That sort of result suggests that...

    HSC verbs confusion

    You might find this previous BoS thread useful: https://boredofstudies.org/threads/difference-between-evaluate-and-assess.316123/ ‘Assess’ and ‘Evaluate’ do overlap a fair bit; in an ‘assessment’, you’re generally given some criteria against which given data should be compared, whilst in an...

    Why does the base and number have to be positive for logs?

    I did include ‘but this might be too early for you OP if you are doing stage 5 maths.’ It actually sounded like OP might be doing Yr 11 maths even though they are in Yr 10. Generally, I think it’s a better approach to teaching to say ‘yes, you’re right, but that’s something you’ll learn about...

    Why does the base and number have to be positive for logs?

    log-2 (-8) isn’t defined in the real plane of numbers, but it is with complex (real + imaginary) numbers which is explored in Yr 12 extension 2 maths. I highly recommend this YouTube video (www.youtube.com/watch?v=9D62oOf7k2A) for those who have already covered complex numbers, but this might...

    There are two separate questions in the original post. I would imagine rankings for each subject are determined the same way most schools are and equal positions would be common. WRT Dux, there are usually several students with ATARs of 99.95 and they are each conferred the title. Several...

    CASIO fx-8200 AU - new calculator coming next year.

    I fail to understand from your explanation why it is cheaper. If it does have all the features of the 100 plus new additional features, then unless retail stores discount their stock of 100’s, they will likely be left with unsold 100’s. Surely Casio won’t want to upset their relationship with...

    equations of motion

    In this scenario, neither u nor v are 0 m/s. If an object is stationary (initial velocity of 0 m/s), it will not move upwards on its own accord; the only force acting on it is gravity which is in a downward direction.

    Chemistry Pract Assessment

    OP, if not already stated in the task description, state that the designed practical is "to find the chemical composition of zinc in ZnCO3 of the given mixture". Any thing else would be unreasonably difficult.

    Chemistry Pract Assessment

    Can you assume that the only zinc present is as ZnCO3 (ie. there’s no zinc in the unknown soluble salts)?

    80+ ATAR still attainable?

    Yes, it is attainable. Your current trajectory is probably below an ATAR of 80, so you‘ll need to put in more effort, but you’re less than halfway through the assessment component, so you can work on the other eighty percent of your marks.

    Should I drop physics?

    Deciding whether to continue or drop a subject is a totally personal decision impacted by many variable factors that only the individual can assess, however a few points worth mentioning from your past and present subjects: You have already completed HSC maths and engineering subjects - if you...
