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?”

So many students wait until they feel motivated or have a solid study plan before they begin 🙅‍♀️🙅
But in reality, motivation usually comes after the first action is taken. You don’t need the perfect plan. You just need the first step. 
Start small. Just start.
What does a week at CoWorks look like?
It’s not just one session. It’s not just one weekly touchpoint.
It’s a full system of support designed to build confidence and keep students consistently organised, proactive and motivated across the week.
We still have a few places available for Year 12 students across our campuses. If you’re interested, we’d love to invite you to a free 7-day trial so you can see why students choose CoWorks.

April Study Bootcamp is coming...
The April holidays are a critical time for Year 12 students preparing for the busiest assessment term of the year. While a short break is important, using some of this time to get ahead can make a huge difference for Term 2.
At Bootcamp, students will:
✅ Build essays for upcoming texts and modules
🎯 Practice exam-style responses for completed topics
💡 Strengthen readiness for Term 2 assessments
For Year 11 students, one third of the year is already complete. With only two terms until the HSC year begins, this is the perfect time to consolidate preliminary topics and build strong foundations.
Across the 4-hour structured session each day, students tackle English and other key “frog” subjects to ensure meaningful progress before the term begins.
