What are the main challenges you need to overcome and secure your best grade in O-level Chemistry?

Overwhelming Content

There is too much content in Chemistry and too little time. Students struggle with major topics like Acid, Bases and Salts, electrochemistry and Organic Chemistry.


Misinterpreting the question will affect the extended parts of the exam question. There is a high cost to going off track from the start of the question. Furthermore, it implies that there are more misinterpretations of similar questions.


Most of the questions require application. With most students adopting passive forms of learning like reading, highlighting, and copying textbooks, they struggle to answer application questions. In O levels, application questions take up a large section of their entire O level grade.

What students say about us

My son, Bryan, scored A2 for Pure Chemistry. It's almost like a miracle as he was failing in Sec 3 and in Sec 4 mid year the school even asked him to drop Pure Chem for combined science.

Fortunately, he persevered and scored A2! I would like to thank Indigo for making this possible.

Felicia, Parent
S4 Express Chemistry

I achieved A2 for Chemistry for my O-levels. I am pretty satisfied with the results as I would usually get B or C during school exams. The notes provided by Indigo helped greatly as they are well summarised and their tutorials I attended made concepts clearer. Preparing for my major exam was less stressful thanks to Indigo and their supportive tutors.

​Jovan Quak
S4 Express Chemistry, SJI

Because of Indigo, I was able to gain better exposure to common Chemistry Questions that were tested on in the O-level paper. Most importantly, I gained confidence in Chemistry and I grew to love the subject even more.
