Hi XXXX,
As promised two weeks ago, Mathematics and Extension 1 Silver edition subscribers can now see the 2018 HSC analyses in all topics.
Lots of interesting stuff jumped out when we took a good look at the past HSC trends. While our philosophy is firmly to prepare for every possible question, we also see sense in weighting revision slightly toward more likely topic areas. No program works harder than SmarterMaths to help you revise efficiently.
If you haven't used this program feature before, some examples of the information we research and highlight to teachers and students for 2018 are included below:
- Topic 14, Mathematics course
Exponential Growth and Decay (4.1%) has produced the highest mean marks of any sub-category within Topic 14, although the simultaneous growth and decay of fish populations in the 2013 exam caused major problems and deserves particular attention. - Topic 11, Mathematics course
Simpson's and Trapezoidal Rule (2.6%) Beware of the myth that Simpson's Rule and Trapezoidal rule questions are the easiest marks in the course. While the standard formula and calculations are generally well answered, the follow up questions have produced horrible results (sub-50% mean marks in 5 out of the last 7 years, including 2017). - Topic 14, Extension 1
Rates of Change (3.9%) has been asked in 9 out of the last 10 years (omitted only in 2015). The 2017 exam's 1-mark allocation was an outlier with all pre-2017 questions worth between 3-6 marks.
Pitfalls: The use of non-right angled trig in this context was examined in 2013 and poorly answered. Not tested again since and worthy of a revision focus.
... and this is how it appears in your worksheets (at a click)!
Thank you for choosing SmarterMaths, and you can expect more enhancements and features coming this year!
