How to work through the CSS Environmental Sciences syllabus
The outline on this page is arranged the way the syllabus itself is: subject, then chapter, then topic, then sub-topic. That last level is what most study plans skip, and it is where coverage actually goes wrong — a chapter marked "done" often has three sub-topics inside it that were never touched.
Weight your plan accordingly: Environmental Pollution and Control carries 19 topics while Global Initiatives and Multilateral Agreements carries 11. Giving both the same number of weeks is the most common planning mistake for CSS Environmental Sciences.
The ~70 hour estimate above is a first pass only: roughly 45 minutes per topic plus 12 minutes per sub-topic. Revision cycles, past papers and mocks sit on top of that number.
