Practical Skills and Core Practicals

Practical skills are assessed in all three Edexcel A-Level Biology papers, particularly in Paper 3. You must be familiar with the 16 core practicals and be able to apply practical skills to both familiar and unfamiliar experimental contexts. This lesson covers experimental design, variables, reliability, accuracy, precision, and an overview of all 16 core practicals.
