Exam tips…

I make these general suggestions without having looked at the exam in detail (and having made them already in class on Thursday).

  • Memorise the relevant equations. You will be provided with the standard HSC formulae sheet (check it out here). There are quite a few important ones missing, especially Snell’s law (refractive index version) and the useful expression of the inverse square law. For a summary of all equations you’ll need to know, look here.
  • Look carefully at calculations before doing them.  Do you need to do any conversions? (eg. kHz to Hz, kilometres to metres etc). Have you been given the angles from the normal? Write down the relevant equation before substituting your values in.
  • Answer the question.  If you are asked (for example) to give two similarities and one difference, then make sure you give two similarities and one difference. If you are asked to include a diagram then include a diagram.
  • Label your axes on graphs, include units whenever they exist, make sure you graph things the right way around – “A vs. B” means A is on the vertical axis.
  • Go over the syllabus – it won’t take very long.  Just scan through it and make sure you know what each point is talking about.  You can’t be examined on anything else.  Here is a copy of the syllabus.
  • Don’t leave anything blank If you get stuck, remember that there is a good chance you will know how to answer most of the questions, and that there is a good chance you know how to do most of the calculations.  Just think about it for a bit longer and don’t assume you can’t answer it.
