# Understanding how molecules bond in 3D – Hybridisation

Hybridisation is useful to understand for the GAMSAT at face value, and also to gain a deeper understanding of more difficult organic chemsitry concepts. For GAMSAT, focus on sp, sp2 and sp3 hybridisation. You can understand hybridisation the quick way or the more in depth way. The quick way is mostly about simply matching the […]

# Sitting the GAMSAT? 5 reasons why you should embrace winter.

Today is the first day of winter. Where I am at least, it is sunny with not a sign of rain. But no matter what the weather, the 1st of June in the southern hemisphere is a reminder that there are officially three months of (more often than not), rainy and cold days ahead in most places. The sun […]

# 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. […]

# The 7 days of GAMSAT

Everyone has their own ideas about the best way to prepare for GAMSAT, but one thing is certain, you can’t do it in a week. So what do we at cbsquared feel you should be doing in that final week leading up to possibly the most nerve-wracking day of your life? Here are our recommendations-but […]

# Acids & Bases: a Guide to Tutorial 9 (Part 1)

Acids and Bases is quite a conceptual topic, but you don’t have to end up in the trenches over it. Listed here is a summary of the focus areas of each question from Topic 9 of the cbsquared Chemistry for GAMSAT course. With some hints and tips to hopefully steer you on the right track and […]

# 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: […]

# Lewis structures sending you looney?

Drawing Lewis Dot Structures is an important skill that underpins your understanding of how atoms are connected, and paves the way for understanding of more complex concepts like intermolecular forces, resonance and retrosynthetic analysis, which are key testing areas for the GAMSAT. Many struggle with Lewis dot structures at first because you really have to dive […]

# Take the Pressure Down: Understand Equilibrium!

Understanding the concepts behind equilibrium can really pay off in the GAMSAT. This is because if you are asked a straight out equilibrium question, such as “what is the equilibrium expression for the following equation…” it can be relatively easy marks. But also because understanding equilibrium is a must if you want to nail some more tricky […]

# 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 […]

# Molecular orbitals don’t have to send you into orbit!

One of the first topics that I’ve found students really being to freak at is hybridisation and orbitals. We tackle it early on in the Chemistry course, because an understanding of hybridisation and orbitals makes a lot of more tricky chemistry that we cover later, a lot easier. Hybridisation is important as it explains the polarity of […]
