Lessons for C2.2 Neural signalling - IB

This lesson delivers structured, step-by-step lessons that guide students through every part of the IB Biology syllabus for C2.2 Neural signalling. These lessons simplify complex ideas like molecular biology, evolutionary mechanisms, and homeostasis, while worked examples show how to approach IB-style questions.

Designed for both HL and SL learners, RevisionDojo lessons ensure students not only understand the theory but also know how to apply it in IB Paper exam situations.

With clear explanations, active learning checks, and a syllabus-first design, RevisionDojo makes revision less overwhelming and more effective.
