Practical skills — IGCSE Marine Science (0697) questions by topic
Seven questions ask you to interpret a Marine Protected Area species count, evaluate a method testing carbon dioxide solubility at different temperatures, or make an accurate scale drawing of a lanternfish, worth between 9 and 17 marks.
Explain, suggest, draw, calculate and name test practical method and data-handling skills specifically, not just content recall. Drawn from 2024 and 2025 papers across these 7 questions, this page's instant marking is well suited to checking precision: a marker's feedback on whether a scale drawing is accurate, or whether a calculation used the correct units, catches errors of technique that content revision alone would not fix.
