Every topic is a case. Every answer needs a witness.

Thirty-five pieces of Marine Science, broken down like evidence: a plain name first, the exam's own term right behind it, and — where it matters — a worked number so a graph stops being a wall of dots.

Built around the two things that have been costing marks: reading a graph before you calculate from it, and writing the four-part case file — Name it, Explain it, Prove it, Judge it — instead of losing the structure mid-answer.
