Chemistry O Level Tips and Tricks

Chemistry can be a subject that requires a lot of memorisation and most importantly, conceptual understanding. These following tips are some elements that you can incorporate into your studies to achieve greater comprehension!

1. Make your own notes (mind maps, flowcharts etc.) — don’t focus on pure aesthetics but make sure that what you’re writing contains a certain element of sequence and logical flow to help you understand the concepts better
2. Identify the common equations that need to be memorised (e.g. combustion of hydrocarbons CxHy + (x + y/4) O2 -> xCO2 + y/2 H2O) and commit them to memory
3. Practice, practice, practice!

• Content like mole calculations and qualitative analysis (QA) may seem straightforward in nature, but chemistry is all about application. After completing your notes for a topic, test your true understanding of the content by attempting different questions. Identify the question types you are weaker at or areas you are less familiar with and work on them!
