VCE results are out! Some schools shine spectacularly in one or two VCE subjects compared to all their other VCE subjects. For Mentone Girls’, it’s Psychology. For Eltham, it’s VisComm and Literature. For Fintona, it’s Accounting and Economics. Is your school on the list?
The percentages show the proportion of reported VCE study scores ≥40 (2022 data) that were from each particular subject. Consider giving those teachers a pay rise… 🙂
My Kennedy College students worked tirelessly to climb to the top of the small schools (≤50 students) leaderboard for the Education Perfect Science Championships 2021. The competition is open to schools of any size in Australia and New Zealand. We came first out fo 248 small schools who participated.
I’m very proud of their achievement.
While this competition was online, there will probably be more opportunities to compete with other schools face-to-face in 2022 (depending on covid restrictions!)
In this analysis, I defined “high-achieving students” as those who achieve at least 2 study scores ≥40. I then compared this with enrolment data to see how their subject choices differed from that of all students (from VCAA statistics).
Choosing these subjects doesn’t guarantee you a high grade. But it does provide some interesting insight into the patterns of high-achieving students, who are more likely to have chosen Specialist Maths, Latin, Chemistry, Global Politics, Physics and Literature.
Examination reports are very useful but most students don’t read them. I’ve scoured the examination reports from 2017, 2018 and 2019 and analysed how many marks were awarded for each topic of the VCE Chemistry course, and recorded what percentage of students got these right. As usual, this revealed that VCAA asks more questions on topics that students frequently get wrong.
Tip for students: focus more of your attention on the red topics in the chart above.
Chapter numbers refer to those used in the Heinemann Chemistry 2 textbook.
Students obsess over significant figures and mole calculations… but these are only worth 1 and 16 marks, respectively in the final written examination. Over two-thirds of the marks in the VCE Chemistry written examination are awarded for written responses where calculations are not necessary.
Tip for students: focus on perfecting your written responses such as explanations of bonding, chromatography, protein structures, and, most importantly, critiquing experimental designs.
This book is a collection of lies we taught to our Year 12 Chemistry students in their graduation year.
The lies include well-meaning simplifications of the truth, mistakes in the textbook, and, in a few extreme cases, blatant falsehoods.
This book isn’t a criticism of the VCE Chemistry course at all. In fact, I wrote this book to demonstrate the overwhelming complexity of Chemistry and the consequential need to make appropriate omissions and generalisations during our teaching as we tailor our lessons to the appropriate year level of students.
Rules taught as true usually work 90% of the time in this subject. Chemistry has rules, exceptions, exceptions to exceptions and so on. You’ll peel pack these layers of rules and exceptions like an onion until you reach the core, where you’ll find physics and specialist maths.

Bisphenol A, or BPA, is used to line food cans and also to make strong plastic baby bottles. Eating large amounts of canned food – particularly canned soups or drinking hot liquids from baby bottles – can result in elevated amounts of BPA being detected in people’s urine. BPA acts as an estrogen mimic – albeit a very weak one – and some research has suggested a link between large doses of BPA and an increase of blood pressure. While this does sound worrying, remember that the dose is extremely important and that the molecules of BPA that do leech into food are too few to have any measurable effect.
The United States Food and Drug Administration (the FDA) conducted a four-year review of over 300 scientific studies and concluded that the traces of BPA that do migrate into canned food are so tiny that they have no effect on human health.
The decision to abandon the use of BPA in baby bottles was therefore based on public pressure not based on safety or on scientific evidence.
The science never suggested there was any safety concern with BPA.
Each year, the VCAA subtly upgrades the VCE Chemistry data book. Each year, I print it and annotate it to show students the wealth of useful information hidden within it (most of which, is in plain sight).
This year, the VCAA has changed some “constants” and added some interesting functional groups to the spectroscopy tables. Smaller things are changed, too. All the protons in the 1H NMR table are now in bold; not just the ambiguous ones.
Start using this annotated version of the data book for your year 11 and year 12 chemistry homework exercises. While you can’t take this annotated version into the final examination (or into most SACs), seeing the annotations frequently throughout the two years will help you find things faster in the final examination.

After several hurdles, I’m happy to announce that Fighting Chemophobia is now available on Amazon in both paperback and Kindle editions for international delivery. Amazon.com and three other independent online book vendors have signed up to stock Fighting Chemophobia.
Buy your copy by clicking the links below – or search Amazon.com or your Kindle device for Fighting Chemophobia to download the book.
Signed copies are of this new third edition are of course still available via this website. Click the PayPal link below to order your signed copy.
I’ve been working on some exciting things in the last few months. Watch this space for teasers.
The second batch of Fighting Chemophobia books are finished! After a long search, we have finally found two great companies for printing and distribution in China. Dianzan design and printing company has laid the book out with great care and precision and turned Fighting Chemophobia into an excellent-quality product in both hardback and paperback editions. The 80 gsm Dowling paper feels great, and there are even some full-page colour images scattered throughout the book. Shunfeng Express is handling cheap, quick shipping and is currently achieving 2-day deliveries within China. They predict 7-day delivery times internationally.
This second batch is higher quality than the first. I’m sure you’ll love what these people have produced.
Working with a publisher could have saved me the search for an editor, a printer, a distributor, a marketer and a translator. Self-publishing has been more rewarding in this regard: not only have I selected the people I’ve worked with to bring this book to completion but I’ve probably learned more this way about the process of writing, editing, printing, binding, marketing and distributing a book than if a publisher had handled the entire process on my behalf.

Chemophobia is an irrational fear of chemicals. It includes the fear of sugar in food, formaldehyde in shampoo and aluminium in vaccines. Fitness bloggers, quack doctors and even small cosmetic companies take advantage of these quirks to sell fake-natural products at elevated prices. Almost always, the same people who spread a fear of ‘chemicals’ also have ‘chemical-free’ products for sale.
Some companies sell “natural”, “organic” and “chemical-free” products to combat the supposed onslaught of chemical pollution in conventional consumer products. Most of these alternative products are no less synthetic, and no safer, than conventional versions despite commanding much higher prices.
Chemophobia is spreading despite our world becoming a cleaner, safer place. People are becoming healthier, and product safety regulations are becoming stricter. The supposed onslaught of chemicals that these special interest groups describe simply isn’t happening.
Perpetrators of chemophobia create unnecessary guilt, stress and anxiety as consumers worry about making the right choices for their family. Consumers are the victims in this battle as pro-natural and anti-natural businesses spread fear about each other’s products.
This book analyses psychological quirks, evolved millennia ago, that prime us to fall victim to chemophobic ways of thinking such anorexia, a fear of vaccines, a fear of fluoridation or a dangerous fear of synthetic medicines. It explores how consumers, teachers, doctors, lawmakers and journalists can fight chemophobia by tackling the social issues that underpin it.
