Thinking About Thinking. The 20-80 Principle

Feb 22, 2014

This week is a good time to stop to think, about thinking. The HSC can be a frantic and stressful time.

The students who perform best are not necessarily the brightest or those that dedicate countless hours to studying, but rather those who have been the smartest in their approach to the tasks that they do and how these are done. These are the students who are organised and manage their time to ensure that the work that they are doing, is structured in a way that will best set them up for assessments and to sit those exams at the end of the year.

We like the idea of the Pareto Principle. This is based on the idea that 80% of effects come from 20% of the causes. This was originally discovered by Italian economist Vilfredo Pareto when he noted that 20% of all pea pods in his garden contained 80% of peas. This is now applied across a broad spectrum of fields including maths, science, business and most relevant to you, the HSC. The 20-80 principle is the perfect way to think about your HSC. 20% of the work you do is going to account for about 80% of your marks. Whilst others around you may seem to be putting in many more hours than you, this is often misguided and ineffective, such as the highlighting of notes or just writing out quotes.

You can be much more effective when you are doing practise exam styled questions or putting yourself under time conditions to simulate what sitting the HSC is going to be like. This reduces the stress that is so commonly felt whilst still making sure that you reach your HSC goals.

Remember the HSC is not a test of pure intelligence, rather a test of competitiveness,that is a combination of preparation, perfect exam technique and the ability to perform well under pressure. When studying, always ask yourself, “Is this a 20% task?”

Year 11 is all but over. Year 12 HSC Exams are still 30 days away.
So what does a CoWorks session look like right now?
For our Year 11s, prelims might be over but that doesn’t mean there’s “nothing to do”! This is the perfect window to get proactive: review what you learnt from prelims, understand your Year 12 syllabus, look at past HSC papers and start building the knowledge and exam skills you’ll need when Year 12 begins on 12 October.
For our Year 12s, it’s all about turning the lessons from Trials into action. Filling knowledge gaps. Refining and resubmitting responses. Closed-book recall. Exam simulation. Targeting those subjects and tasks you’d rather avoid and making every remaining moment count.
No wondering “What should I work on today?”
Students walk into their CoWorks session with a clear plan designed around exactly where they are in their HSC journey 💪

Then it’s time to turn your attention to the final stretch. Trials aren’t meant to be perfect. They’re exactly what the name suggests, a trial run for the real thing.
So embrace the mistakes. Look closely at where marks were lost. Get feedback. Work out what needs to change and adjust your approach.

You’ve come this far. You’ve got this. 💪
