HSC Biology and Chemistry tutoring for Years 11 and 12, prioritised against seven years of past HSC papers, 605 questions and 1,400 marks, so revision time goes on the topics that have earned it. Taught by a current HSC science teacher, online now to students anywhere in NSW.
Most revision advice is a guess dressed up as confidence. I'm Kyle James, a current NSW HSC science teacher, and instead of guessing, I indexed every question in the 2019 to 2025 HSC Biology and Chemistry papers by topic, marks and difficulty, then applied a fixed rule to find out which topics the papers actually keep coming back to.
That analysis is published in full, not just quoted at you, on the Biology and Chemistry breakdown pages, so you can check a label rather than trust it. Tutoring sessions use the same evidence: the topics below get first claim on revision time because seven years of papers say they earn it, and the rest of a session still targets whatever your school's assessment calendar has coming up next.

It is not a prediction and it does not reproduce any NESA exam question or marking-guide text, only statistics derived from seven years of past papers. A topic in four or six of seven papers may simply have been on a rotation.
Biology and Chemistry are not directly comparable. Chemistry returns to the same topics year on year, so its bar is set higher; Biology rotates through a much wider syllabus, so its bar is set lower. Each subject uses its own rule, published on its own breakdown page, for exactly that reason.
Your year, your subjects and the topic that is not landing. That is the whole enquiry, and it costs nothing.
High-yield topics get first claim on revision time, then the rest of a session still targets your school's own assessment calendar and trial dates.
Most lost marks are not lost knowledge, they are answers that never said the thing the marking guidelines wanted. We fix the writing, then the marks move.
It is a structural label, not a prediction. Every question in the 2019 to 2025 HSC Biology and Chemistry papers was indexed by topic and marks. A topic is labelled high yield if it appeared often enough and carried enough marks across those seven years to clear a fixed rule, published in full on the breakdown pages. It tells you what the paper has rewarded, not what is coming this year.
Yes. The full topic-by-topic breakdown for Biology and Chemistry, including the exact rule used and every topic that did not make the high-yield list, is published on their own pages. No exam question wording or marking-guide text is reproduced, only the derived statistics.
Physics and Maths tutoring are both available, but this topic-yield analysis currently only exists for Biology and Chemistry, so the same high-yield claim is not made for those subjects. Mention Physics or Maths on the enquiry form and sessions will still be built around your actual syllabus and assessment calendar.
Sessions run online now, live over video, to HSC students anywhere in New South Wales, including Sydney, Newcastle, the Central Coast, Wollongong and regional NSW. In-person places on the Central Coast open from December 2026.
One-on-one tutoring is $100 per hour. No lock-in contract, no joining fee. Small-group classes are priced per program and work out cheaper per hour. There is no charge to enquire.
Tell me which topics you are losing marks on and we will work out where the fastest gain is. Pick a time that suits, and you have an answer today rather than after a week of emails.
Would rather write than talk? Send a message instead and I will reply by email, usually within 24 hours.
Tell me your year, your school and what you're finding tricky, and I'll get back to you by email. No payment required to enquire.
