Why a custom quiz beats a generic one

Many students look for a ready-made biology quiz on BBC Bitesize because it is free and matches the curriculum, but a fixed quiz only covers what its author chose. A quiz built from your own lecture slides or revision notes tests the exact topics your teacher covered, including the terms and examples you were given.

Test the exact topics on your syllabus rather than a general selection
Use multiple-choice, true/false or short answer to match your exam style
Read an explanation for every answer, right or wrong
