Hi XXXX,
Our HSC analyses for the 2018 Mathematics and Extension 1 exams have now been rolled out!
Over a thousand HSC teachers now produce the most up to date, high quality HSC revision resources for their students using our program.
But don't take our word for it!
See for yourself in the attached free HSC anlaysis and worksheet that you can use as a revision resource for your students, no strings attached. You can download the free worksheet here:
Mathematics Extension 1, Topic 14, Rates of Change
A sample of the type of information we research and highlight to teachers and students (and make available in all topic revision resources) is 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)!
