    How tf do you guys memorize every intricate qualitative part of this subject?

    I felt the same way regarding all the little rules and tricks of information to remember in order to answer questions. You just have to look at lots of resources and do a lot of questions and you'll start to become very good at some common questions, and realise what information never shows up...

    hsc physics (pre 1995)

    Well all you need to do is go to UNSW and find it and look at whatever you need. You said you'd give an arm and 3 legs to get it, time to put your money where your mouth is.

    question

    There are two approaches. First you could think that either N is to the left of U or it isn't, and there is no condition that makes one possibility more likely so there are half as many ways as if there were no restrictions. Thus 6!/2 = 360 ways Or, visualise just N and U already being there...

    Can there be perms and combs in ext 2 papers?

    Ps and Cs are not in Ext. 2 under the new syllabus. The only slim possibilities I can imagine are using pigeonhole principle in a proof and understanding what a factorial is.

    Trig identities question

    Factorise the numerator as the difference of two squares and factorise the denominator by taking out cos(theta). A factor of cos theta + sin theta will divide out and the result should be obvious.

    Economics

    I can give a bit of advice since I do an eco major at usyd. If you meant 'advance maths' as in the course 2u maths, then according to the uni thats the assumed knowledge. I'm not sure if they actually check that since when I enrolled in my econ class, it only came up with a message saying that...

    Math1081 Course Review (Upcoming) [IMPORTANT FOR PEOPLE WHO WANT TO STUDY CS]

    Some suggestions; 1. Maybe we could add in advice about the teaching team for each subject. Like each contributor discusses about their lecturer/tutor (perhaps identifying them with their initials only to avoid privacy concerns). 2. You could make a point about whether or not the textbook is...

    Uni Course review

    Will there be a verification to show that each contributor actually did those subjects? I'll be happy to participate, the only caveat is that USYD's exams finish June 17 and results release 5th of July so if you want to wait for us there will be a bit of delay.

    can you lose a mark if a question asks two identify two things, and you identify three of which only two were correct, can you still get two marks?

    My school had a policy where in a case like this they would only look at and give marks for the first two listed, ignoring whatever was the third one written down. So follow the question instructions.

    Do any of your schools steal trial questions?

    It happens everywhere all the time, teachers become too fed up making questions and see attractive questions in other papers for them to use. It's particularly a gold mine for math because they know students avoid papers from 2019 and before since they are old syllabus, but a lot of the...

    They differ by a constant so they are both correct antiderivatives. To check without a graphing calculator, just differentiate and see if you get the original function.

    Can I get into Extension

    4 tests for year 10 maths? Wow, that's a lot. At my school we had an online test (I did year 10 in 2020), then an assignment, and then 2 in-person tests. The good news for you is that schools generally put a greater weighting on the tests later in the year, particularly if one of them is a...
