With a decade of teaching experience coupled with a career in the financial industry, Mr Koh has been featured in a number of news and magazine articles.

He has written for the Asian Journal of Public Affairs and other Economics articles written by him are also publicly available.

Mr Koh adopts a parachute and a risk-based approach. The aim is simply – to cover the entire ‘A’ Level Economics syllabus in the most fuss-free and efficient way possible.

Parachute Approach

We all know how content-heavy the Economics syllabus is. How the parachute approach works is that Mr Koh distils each chapter into umbrella concepts (covering a range of related sub-concepts), which can then be EASILY parachuted into students’ essay answers. This is not just a time-saving skill which forces students to focus on the key concepts, but it is proving to be a crucial skill, given Cambridge’s shift towards critical-thinking questions in recent years.

Risk-based Approach

The risk-based element means that resources are directed towards areas which carry the greatest weight in the ‘A’ Level examinations - hence the higher ‘risk’ associated with them. As a result, Mr Koh has chosen to focus on the skills involved in writing economics essays, since the essay paper alone accounts for 60% of the total score for H2 Economics. Case studies are quintessentially essay questions broken down into many parts, overlaid with the need to relate data from the extracts. The higher order questions in most case study exercises usually constitute 6–10 marks each, which make them no different from essay questions. Based on a breakdown, it is fair to say that more than 80% of the final assessment depends on a student’s ability to produce good essays.


Mr Koh’s teaching mantra is that while Cambridge can vary the way their questions are phrased, they cannot test students on concepts which have not been taught before (i.e. not in the syllabus). Hence, being able to see through a question to pick out the focus, and subsequently apply the parachute concepts is an important skill which Mr Koh inculcates in his students.
