Chemistry quizzes built from your own course material

Most chemistry courses test you on specific definitions, worked calculations and concepts from a particular unit, so a generic quiz rarely matches what will be on the exam. A chemistry quiz made from your own lecture slides or notes targets the material you were actually assigned.

  • Questions are generated from the material you upload, not from a generic bank.
  • Multiple choice, true/false and short-answer formats with explanations.
  • Free plan includes 3 generations per month and browser study.
  • Plus and Pro add exports for PDF, DOCX, Anki, CSV, QTI 2.1 and Moodle XML.
Example general chemistry quiz questions
What is the charge of an electron?Negative, about -1 elementary charge. It balances the positive charge of the protons in a neutral atom.
True or false: Avogadro's number is about 6.02 × 10^23.True. It is the number of particles in one mole, so 12 g of carbon-12 contains about 6.02 × 10^23 atoms.
What type of bond forms when two nonmetal atoms share electrons?A covalent bond. Sharing lets each atom reach a stable outer shell without fully transferring electrons.
What is the pH of pure water at 25 °C?7. At 25 °C, hydrogen and hydroxide ion concentrations are equal, each 1.0 × 10^-7 M.
What happens to reaction rate when temperature rises?It increases. Molecules gain kinetic energy, so more collisions exceed the activation energy.

Quizzes from your own material

Upload a PDF, DOCX, PPTX, plain-text notes or a photo of a textbook page, and get questions based on that exact content.

Three question types

Multiple choice, true/false and short answer, so you can test recall and application, not just one format.

An explanation for every answer

Each question shows why the correct answer is right, so a missed question becomes something you learn from.

How it works

Upload your chemistry material

Add lecture slides, a chapter PDF, typed notes or a photo of a page. Text recognition reads the photo.

Choose the question types

Pick multiple choice, true/false, short answer or a mix, and generate the quiz in one pass.

Take the quiz and review misses

Answer in the browser, read the explanation for each miss, and retake the missed items later.

Quizzes are most useful when you attempt them before checking your notes. Work through the questions, read the explanation for every miss, then retake the missed items after a day or two so the answers stick.

DeckOwl doesn't award certificates. If a course or program requires one, check with your instructor or the platform that issues it. Your quiz results and explanations are a record of your practice that you can keep.

Frequently asked questions

Does DeckOwl give a certificate after a chemistry quiz?

No. DeckOwl does not issue certificates. If a course requires one, ask your instructor or the platform that issues it.

How many questions should a chemistry quiz have for one unit?

Ten to twenty questions per unit is a common range for general chemistry. Mixing question types catches gaps better than repeating one format.

How should I study with a chemistry quiz?

Answer without notes first, then read the explanation for every miss. Retake the missed questions after a day or two so the answers stay in memory.

Can I export a chemistry quiz to PDF or Moodle XML?

PDF and DOCX export are included in Plus. QTI 2.1 and Moodle XML export are in Pro, and the free plan is for studying in the browser.
