This resource is designed for Cambridge IGCSE Marine Science 0697 (2024–2026 syllabus) and provides structured, outcome-based practice for both Paper 1 and Paper 2. Each chapter includes short teaching content followed by past paper style questions and differentiated worksheets that can be used in daily lessons. The recommended lesson structure is 30 minutes of focused teaching and 15 minutes of worksheet practice. The worksheets include a variety of question types such as drawing and labelling diagrams, matching exercises, structured questions, investigation questions, data handling, calculations, and graph work. This ensures students practise all skills required for the examination. The resource also includes Formative Assessment (FA), Mastery Assessment (MA), and space for tracking student performance. A marking scheme is provided at the end of each section to help teachers mark consistently and to support home learners with self-assessment. All keywords and content strictly follow the Cambridge syllabus and textbook guidelines. This workbook prepares students effectively for mock exams, term exams, and the final IGCSE examination while allowing teachers to modify details to suit their class needs.
