    Tutorials before Lectures?

    Timetables got released yesterday and there's a trend in my timetable where my tutorials are conducted before my lectures. Is this normal? I thought tutorials are where you ask questions based from your lectures, so would it still work out if my tutorials are before lectures? Advice would be...

    ATAR Estimate! From Year 11 marks

    Don't bother with estimates from your Y11 marks. Things change in Y12.

    am i too dumb for chemistry?

    I really enjoyed Economics (particularly Y12 Economics). If you follow current affairs on the Australian and global economy, you’ll enjoy Eco. It’s very content heavy and some topics you’ll dislike more than others but the best way to study for Eco is to keep up to date facts (RBA’s cash rate...

    How to study and improve for chemistry and Math Extension 1 for the Holidays?

    For Chemistry I'd recommend going over your basics from Y7-10 and if time permits, try and start Module 1 from Year 11 to get a head start. Studying for Mod 1 (based off memory) is mainly just memorisation/understanding of content. For Mod 2, you'll start working with mole calculations. You...

    am i too dumb for chemistry?

    I'd say keep Chemistry. I severely disliked Chemistry back in Year 10 as I found it difficult at the time. However, I found it very enjoyable and quite rewarding during Y11/12 and by the end of my HSC, it was my second best subject. You'll have plenty of time to build up your knowledge over the...

    Chemistry New Syllabus Advice / Sample Answers by an Experienced HSC Tutor

    For complexation reactions, do we memorise all the complex compounds that form? I'm unsure of which ones to remember.

    Chemistry New Syllabus Advice / Sample Answers by an Experienced HSC Tutor

    Hi Jazz, had a few more questions. 1) Which precipitation titration methods should we definitely know (would Fajan's method be one we need to know)? 2) For the last dot point of Mod 8, could they expect us to remember a specific process and write a whole 8 marker response to it? That is, if...

    Chemistry New Syllabus Advice / Sample Answers by an Experienced HSC Tutor

    You mentioned integration in your answers for HNMR. Is there a way to calculate the integration in the exam if they're not provided? My teacher said it's very unlikely they'd ask us about integration, hence why we never were taught of it. But i've seen a few past papers include the term and...

    Do you guys base your estimates off the person's ranks or raw marks?

    Equilibrium Constant & Temperature

    Why does the equilibrium constant get affected only by changes in temperature? Why not with changes in pressure or concentration? Let's consider a general reaction: A + B <--> C + D where Δ < 0 The eq. constant expression would be [C][D]/[A]. If we were to increase the temperature, equilibrium...

    Oh I see, that clears up the confusion. Thanks so much!
  13. _Anonymous


    Using the equation Q = mcΔt, if Q is positive; the reaction is said to be endothermic. If Q is negative, the reaction is said to be exothermic. What confuses me is that when we perform the experiment in school, we pour an Ionic compound into a beaker filled with water and measure the final and...

    New Syllabus - Scaling

    Considering the new syllabus for Science and English have become considerably harder than the old syllabus, does this mean that Physics, Chemistry, Bio and English will generally get scaled higher compared to before? Or does it depend more on how everyone does in the 2019 HSC?

    Concentration/Mass Question

    Ahh right, makes sense. Thanks.

    Concentration/Mass Question

    Oh, that makes sense; thanks. I thought that adding water would make a solution diluted, hence they would be the same. Could you explain the difference between one adding water and the other being diluted?

    Concentration/Mass Question

    Yeah sorry, I wrote down question 1 incorrectly. Your method works to get the answer. Thanks. 2) Could you elaborate on how my V2 is wrong? I thought that C1V1 is the equation that applies to the substance before it's diluted and C2V2 is after it's diluted? So how is V2 not 200mL
