Revealed: The secrets behind Sydney's top schools for HSC maths
'We introduced a middle school model to focus on that transition,' explains Victor Newby. 'We now group subjects like maths and science with one teacher, and English and history with another. It means year 7 students have six teachers rather than 12, which helps make that move into high school smoother.'
It was among multiple changes at the inner west high school in 2020, including employing a senior study coach for HSC students, and starting an after-hours algebra club for year 10s.
Concord High is one of several schools to achieve improved average HSC scores in mathematics over the past three years, a Herald analysis of public school final exam results has revealed.
Concord's average HSC score across all maths courses taken has jumped more than three marks to 83.4, placing it in the top five non-selective state schools.
Academically selective school North Sydney Boys High achieved the highest average score in maths, with an average across all maths courses of 91.7.
James Ruse scored an average of 91.4, while Baulkham Hills scored an average mark of 90, narrowly eclipsing Sydney Boys High (89.9) and Normanhurst Boys (89.5). Most fully selective schools offer only advanced maths and extension 1 and 2 subjects, rather than the standard courses.
The analysis, from data published in 385 NSW public schools' annual reports in 2024, reveals those achieving strong maths results across their entire student cohort, not just band 6 results.

First they topped the HSC. Now North Sydney Boys is raising the bar
The head of English at North Sydney Boys High, Loveday Sharpington-Recny, is no stranger to the challenge of keeping teenagers engaged in a novel when they could be flicking through an endless stream of TikTok videos. 'The attention span is always difficult. But there's room for a love of literature and for reading, which we instil from the first day of year 7. We are also constantly challenging students with really high standards,' she says. An analysis of exam results shows North Sydney Boys achieved an average HSC score of 91.5 across all English courses last year, making it the state's top-performing public school in that subject. Sharpington-Recny said enrolments in harder HSC English courses are also rising at the school, with 45 students taking English extension 1 this year, up from 38 in 2024. It has defied the statewide slump in English extension enrolments; two courses in which girls are twice as likely to take the subjects as boys. Loading 'Traditionally, the students are maths- and science-focused, and by year 12 that can be the path they go down. But we find more and more they are interested in taking extension English.' She said Albert Camus' novel The Stranger and T.S. Eliot poems are among the texts year 12 students have most engaged with this year. 'Reading widely is critical for grasping very complex concepts,' she said. 'Do students across the state read enough? No. And it's the same here, and as they get into teenage years they tend to stop reading. We encourage it, provide book lists and ask parents to support reading. The more they read, the better their vocabulary will be.'

'Please try again': KFC questioned over kiosk name blunder
A Sydney KFC location has been called out after one of its kiosks seems to have experienced a hiccup. An Aussie customer shared their photos to Reddit - and it appears they're not the only one who's experienced the blunder. Want to join the family? Sign up to our Kidspot newsletter for more stories like this. Image: Reddit. RELATED: Maccas worker confirms what Grimace actually is 'KFC finds my name offensive' Sydney Reddit user Mitchell has taken to the platform to share an odd experience they had at KFC. Mitchell said that he tried to put his name into the self-serve kiosk - which requires a first name and last initial for staff members to put on the order. But, for him, it just wasn't that easy. 'KFC finds my name offensive,' he said in the post. 'My name is Mitchell. Apparently, because it contains the word 'hell', it's not allowed. I tested by changing the name to 'Hell', and got the same result.' In the photos posted, you can see that when 'Mitchell' was put into the slot, a message came up in red. 'Please try again, this word is not allowed.' But, when he used 'Mitchel' with one 'L', it all worked perfectly fine. RELATED: Fast food etiquette Aussies agree everyone must do 'Did you tell them you're offended?' Commenters on the post thought the mishap was hilarious, cracking jokes about similarly common names which, accidentally, include explicit or suggestive words. 'What a bloody Mitchell…' one person joked. 'Want to know what happens with Cockburn, Dickson, or Butters now,' said another. 'Did you tell them you're offended by them being offended,' a third person said. It's a thing! But, it turns out the issue isn't uncommon, and may have been something referred to as the Scunthorpe problem - the unintentional blocking of online content because the text contains letters which appear to have an obscene meaning. The phrase was named after an incident in April 1996, in which AOL's profanity filter prevented people in the English town of Scunthorpe from creating accounts on the platform, due to the town's name containing a word which I'll let you work out on your own. 'Omg this happened to me.. my name is Cass and it said it was offensive! I guess [because of] the ass,' one user shared. 'Haha stupid tech. Kinda reminds me of the guy called Nasser who had the 'ass' part of his name censored so it came out like 'N***er',' another recalled. 'When Google was changing 'ass' to 'butt' so looking for 'assassins' gave you 'buttbuttins',' a third commenter said. Kidspot has contacted KFC for comment.
