# Making maths in physical chemistry less scary

Once students arrive at the physical chemistry topics of the Chemistry for GAMSAT course, they are confronted with a subset of mathematical skills that are required. The maths is quite straight forward believe it or not, but the big equations and the use of logarithms can make these questions seem more difficult, and let’s face it, […]

# Back to basics: Graphing and the GAMSAT

This week, in the Chemistry for GAMSAT course, we start on the GASES topic. For many, this topic also marks their first foray into maths and graphing as part of their GAMSAT preparation. The GAMSAT is notorious for using graphs to represent data, and for requiring that graphs are interpreted correctly to answer a question. […]

# Back to basics: turning GAMSAT maths into child’s play

Around half of the topics in the Chemistry for GAMSAT course rely on a number of mathematical skills. Despite what you might initially think, the level of maths required in the GAMSAT is not difficult, but it may require a concerted effort to make sure your skills are up to scratch, especially with the no calculator rule. […]

# Using Simultaneous Equations and the Arrhenius Equation

The relationship between the activation energy for a reaction, Ea, temperature and the rate constant is shown by the Arrhenius equation: (A derivation of this equation pops up in ACER Practice Test 1, Questions 49-51) The Arrhenius Equation looks pretty nasty…after all it has a FRACTION raised to the power…with base “e”…eeeee indeed! Also, dragons: […]

# Learning How to Learn for GAMSAT

So you’ve decided to give the GAMSAT a go. You’ve downloaded your ACER practice test and some science materials, but the more you delve into it, the more you realise just how much you’ll need to prepare for the GAMSAT. You begin to feel overwhelmed. You’re not really sure where to start, or if you’re […]

# Logs (in less than 5 minutes)

Students sometimes start to feel a little panicked once they get to topic 7, which refers to logarithms. by

# 17 Equations that Changed the World

Why is it that when we put an ice cube in a cup of hot coffee, we always see the ice cube melt, and never see the coffee freeze? by
