This second edition of the popular Higher Human Biology Course Notes is perfect for use as a classroom support to equip students with key information on the three course units in a bright new layout.
All processes and experiments are explained clearly using a step-by-step approach, whilst diagrams and illustrations support understanding and help students to engage with the text. New topic-specific questions for students help them reinforce understanding and practice assessed skills.
