HSC NEWS & TIPS BLOG
I recently found some incredibly useful videos made by a Sydney Maths teacher called Eddie Woo. These particular videos give an introduction to parametric equations for Mathematics Extension 1 students. Hopefully they're useful to you!
If you’re studying HSC Chemistry, you’ve probably started to encounter equilibrium reactions. From our tutoring courses in the summer holidays, I realised that this can be a challenging topic for many students. Hopefully this article will clear up misconceptions and cement your understanding of the concept.
Nicholas Chang received a perfect 99.95 ATAR and came 17th in NSW in Chemistry in the 2015 HSC. We interviewed him to discuss his tips about studying, exams, and managing stress.
The summer holidays are a vital period for HSC students. This video will give you the skills necessary to use this time efficiently and to prepare effectively for the half-yearly exams.
Transcription: So today we’re going to talk about ‘Long…
The slingshot effect is used by a spacecraft in increase its velocity. To do this, the spacecraft travels close to another moving object such as a planet or moon. As the craft moves away from the planet, it is travelling faster than when it started. However, it is vitally important to realize that its speed relative to the planet is unchanged, only its speed relative to the sun (and other planets orbiting the sun).
Episode 2 of Top Marks QA is on G-Force. Our head physics teacher explains how to derive a formula and calculate g-force in a range of different situations.
Electrochemistry and galvanic cells are an interesting topic in HSC chemistry and although it only has a small section in the chemistry syllabus, a strong understanding is necessary.
The first edition of our Top Marks QA video series is on enantiostasis in HSC Biology. Watch our head biology teacher explain the concept and how to answer specific questions in the HSC.
While there are only two dot points in the HSC Chemistry syllabus dedicated to spacecraft re-entering Earth’s atmosphere, they are commonly assessed in exams. This will be a quick article to outline the issues involved and how to answer those questions.
Biopolymer questions are often a source of trouble for HSC Chemistry students. Every student should have a biopolymer which they can name and describe briefly, but often they don’t have enough information for a 5 or 6 mark question. This guide will make sure you are confident to answer any possible question on biopolymers.
The first module of HSC biology is ‘Maintaining A Balance’,…
Gravitational potential energy (GPE) is the first difficult concept in HSC Physics. This article is aimed to walk you through the concept and make sure that you are comfortable answering questions on it.
As an HSC Chemistry tutor, I observe titration to be a particularly long and confusing process for many students. This article will break down the logic behind each step of the titration process, and furthermore, provide guidance on performing calculations related to titration. It will also run through major cautions that HSC Chemistry students need to be aware of in performing titration.
The HSC begins in less than two months and how you use that time…
In almost every HSC and HSC trial paper for Biology, there is a question on evolution by natural selection which requires you to describe the process, and often apply it to a real or theoretical situation. This can range from "explain the process of evolution by natural selection" to more roundabout questions using models for natural selection based on cookie jars. Regardless, this question will always be there and there is no reason you should ever get less than full marks - providing you follow this simple guide.
Our Head Physics Tutor, Andy Chu, walks you through the topic of black body radiation from the Ideas to Implementation topic. This is a difficult concept and this article will provide the depth of understanding required to achieve great results in the HSC.
Head Physics Teacher Andy Chu discusses his tips for answering long response questions in HSC Physics, Chemistry and Biology. This is a must read if you want a band 6 in any HSC science.
