Why a custom quiz beats a generic one

Upload a PDF, slides, a Word file or a photo of a page, and DeckOwl writes multiple choice, true/false and short answer questions with explanations.

Example GCSE biology revision questions

Which organelle is the site of aerobic respiration?Mitochondria. They release energy from glucose, which is why muscle cells contain many of them.

What type of bond joins amino acids together in a protein?A peptide bond. It forms by condensation between the amino group of one amino acid and the carboxyl group of another, releasing water.

Which enzyme breaks down starch into maltose in the mouth?Amylase. Salivary amylase hydrolyses starch into smaller sugar units that are broken down further in the small intestine.

What percentage of energy is typically passed from one trophic level to the next in a food chain?About 10%. Most of the energy is lost as heat through respiration or is not eaten, so only a small fraction is stored in the next level.

Which type of cell division produces gametes?Meiosis. It halves the chromosome number and produces genetically different haploid cells.

How it works

Frequently asked questions

How often should I quiz myself when revising GCSE biology?

Short, regular sessions tend to work better than one long cram before a test. Retesting topics after a gap in time helps recall stick.

Is testing myself better than rereading my biology notes?

Research on retrieval practice suggests that recalling information from memory helps it stick more than rereading does. A quiz is a quick way to check what you have really learned.

Can I export the quiz to Word or Moodle?

PDF and DOCX export is included in Plus, and QTI 2.1 and Moodle XML export are available on Pro. The free plan lets you study quizzes in the browser.
