25.01.2022 Question from anonymous poster: Tips for Maths Methods? Maths Methods can be a really tough but rewarding subject - the scaling is around +6 or even more from memory if you get a raw study score of 30. The best way to tackle methods is to understand the concepts underlying each question. 44% of the final exam is on worded question analysis so it is integral that you understand the concepts of each topic. ... To help you out, here's two of the most important concepts that you MUST know in order to be successful in this subject - calculus and probability: http://talkboard.com.au/video/vQtPzxnTwwu3ZRWTm http://talkboard.com.au/video/3xTKv2NSx7aRjE4FX Here are two videos we have made on derivatives and markov chains, which we guarantee will pop up on your end of year exam and at least one SAC. The second important requirement of methods is to be able to do questions fast - this subject tests speed as well as accuracy. What this means is that you have to do a lot of practice exercises. It is all well and good to know a concept, but you have to know it like the back of your hand in order to meet the stringent time constraints of the end of year exam or SAC. Be aware that these exams will be extremely long and challenging to sort out the cohort. This is where Talkboard comes in handy - our videos provide excellent lessons on the basic concepts underlying methods and you can re-watch them again and again until you understand that concept.

17.01.2022 This question was posted anonymously; hi i have a question on complex numbers! Given that z is the complex number x+ yi and that... modulus(z) + z = 6+ 2i, find x and y Thanks!!! So, the way we tackle this question lies in defining modulus(z). modulus(z) = sqrt(x^2+y^2) We can also define z as; z = x + yi So we can re-write the expression from the question as; sqrt(x^2+y^2) + x + yi = 6 + 2i Therefore, we can now equate real and imaginary components must equate, so y = 2. Now we can equate the real components, if y = 2, we can re-write the expression as; sqrt(x^2 + 2^2) + x = 6 We can re-write this as; sqrt(x^2 + 4) = 6 - x, then squaring both sides (x^2 + 4) = (6 - x)^2 This simplifies to; (x^2 + 4) = 36 - 12x + x^2 Therefore; 12x = 32 and x = 32/12 simplified x = 8/3 Thanks for the question! I hope this helps!

17.01.2022 Here's a question we received from an anonymous student regarding titration: For year 12 Chemistry, I would like to ask if there are any explainations on what happens to the mol, concentration etc when any titration equipment has been washed? Firstly, when we fill a pipette with solution, we want to make sure it's been cleaned AND dried. If there is still moisture inside it, the solution that we are putting into the pipette will be diluted slightly. This will mean that we ...will actually have less mole in our aliquot than we think, which will affect the outcome of a titration. Secondly, when it comes to the flask containing our aliquot, we are only worried about the number of mol in our aliquot, as it is the number of mol that determines how big our titre will be. Therefore it is ok if the flask is wet, but it still needs to be cleaned. Lastly, like the pipette, the burette needs to be cleaned and dried, otherwise the solution that we put into the burette will be diluted slightly, affecting its concentration, and therefore affecting the size of our titre. Basically, it's important that we know the concentration of what's in the pipette and the burette, so they both need to be dry. On the other hand, we only need to known the number of mol in the flask, so dilution doesn't matter and our flask does not need to be dried after cleaning. When it comes to these sorts of questions, it's helpful to compare the actual concentration (which is affected by errors in washing and drying procedures) with the calculated concentration (the concentration that we calculate when we aren't aware of any of the errors we might have made) in order to see the overall effect of any mistakes. Here's a link to a video that might be a bit more help: http://www.talkboard.com.au/video/bsg6LgnMXcA8cRbu5

14.01.2022 We received an anonymous questions from a user: A rectangular piece of cardboard has dimensions 20cm by 36cm. Four squares each x cm are cut from the corners. An open box is formed by folding up the flaps. Find a function for V, which gives the volume of the box in terms of x. In this question, we are looking to create a function for volume using an unknown variable which we call x.... We are dealing with a rectangular prism or cuboid, so first, we need to define the volume of a cuboid. We know that for a cuboid: Volume = Length x Width x Height Now, we need to define 3 functions that will explain the length, width and height using this information. We know that as we cut out squares this will affect the length and width of our base equally. Also, the length of this square will become the height of our cuboid. So, we can say that Height = x And, as we cut out two squares each time, the length is given by 36cm minus the length of the two squares we cut; Length = 36- 2x Likewise, the width will be the width of our cardboard minus two squares, so; Width = 20 - 2x So, subbing in we can now express volume as; Volume = Heigh * Length * Width Volume = x(36-2x)(20-2x) Taking out common factors Volume = x(2)(2)(18-x)(10-x) Volume = 4x(18-x)(10-x) And this is the function of our Volume equation.

13.01.2022 A question from Joanna Nguyen; How do you guys organize throughout the year? Did you study every single day and do tons of practice exams? Can you share some study tips? What's your biggest advice for VCE students of this year and the coming years? Hey Joanna, ... It's a really delicate balancing act between your studies and your extra curricular activities. Obviously studying everyday was key to doing well, however, be sure not to over study at the start of the year. Give yourself study breaks; aim to study around 2-3 hours every night with breaks every 15, 30, 45 or hour or even more if you can concentrate for that long! Studying is important, but what's more important is that what you're studying you're actually taking in. There's no point in studying but not taking it in. With practice exams, don't start until you've done the entire course because if you don't understand some questions, that may be demoralising. Try to start them 3-4 weeks before the actual exam so you get used to the pace you have to work at, recognise some areas of weakness you might have, and get used to the way they ask you to demonstrate your knowledge. There is no single biggest piece of advice we can give but to try hard, and choose subjects that you actually enjoy! Of course there are prerequisites to courses after high school but make sure you have a mixture of fun and challenging subjects to keep you motivated throughout the year! Thanks for posting and good luck with year 12!

11.01.2022 Another anonymous question: Hey Talkboard, I was just wondering what were some general organisational and overall tips for getting the best marks possible in year 12? Year 12 can be a really stressful year so it helps to be really organised and ready to tackle anything. So that means organising your folders, making sure that your notes are in the right place so that you're not searching everywhere to find the trig formula.... Most VCE subjects require a lot of work, and so you have to be on top of the course. My best bet is to write notes after each lesson so you consolidate your knowledge and don't cram for SACs or exams, as appealing as that may be. Finally, probably the most important tip is to never give up. A poor SAC here or there doesn't ruin your overall subject mark. The final exam is by far the most important assessment, so your study score is not set in stone until you leave your final exam. Good luck!
