05—Tips
ESS Exam Tips from Top Scorers
Use the 1-min-per-mark rule
A 6-mark question deserves 6 minutes. This prevents spending too long on Section A and running out of time for the essay.
Name real examples
IB ESS examiners reward specific, named case studies (e.g., "Costa Rica's Payment for Ecosystem Services") rather than generic statements.
Define before you explain
Start every extended response by defining the key environmental concept. This picks up easy marks and structures your answer.
Quote data with units
In data-response questions, always cite figures from the source: "CO₂ emissions rose from 350 to 410 ppm between 1990 and 2020."
