Why build your own chemistry exam deck

Printable chemistry review sheets are easy to find, but exam questions follow your own lectures and textbook, so a custom set works better. DeckOwl turns those files into chemistry exam flashcards you can study in the browser.

  • Cards come from the exact material your course uses, not a generic list.
  • Spaced repetition brings back the reactions and formulas you are about to forget.
  • Short, single-idea cards are easier to review daily than long answers.
  • Export to Anki or PDF is available on the Plus plan if you want to study elsewhere.
Example general chemistry flashcards for an exam
What is Avogadro's number?6.022 × 10^23 particles per mole, the number of entities in one mole of a substance.
What does Le Chatelier's principle predict?An equilibrium shifts to partly offset a change in concentration, pressure or temperature.
What is the ideal gas law?PV = nRT, where P is pressure, V volume, n moles, R the gas constant and T temperature in kelvin.
What is the difference between oxidation and reduction?Oxidation is loss of electrons and reduction is gain of electrons, which is why the two always occur together.
What is the pH of a neutral solution at 25 °C?7, because hydrogen ion and hydroxide concentrations are equal at 1 × 10^-7 M each.

Flashcards from your material

Upload PDFs, DOCX, PPTX, plain-text notes or photos of pages and get cards built from what your instructor actually covered.

Spaced repetition

Cards return at the intervals where you are likely to forget them, so review time goes to the topics you miss most.

Quizzes and mind maps

Multiple choice, true/false and short answer questions with explanations, plus mind maps that show how topics connect.

How it works

Upload your notes

Add a PDF, slide deck, DOCX, text file or a photo of a textbook page.

Check the cards

Skim the generated flashcards against your lecture and remove anything off-topic.

Study on a schedule

Work through the cards that are due each day until the exam, letting spaced repetition target your gaps.

Start with the chapters your instructor emphasized, then add slides and worked examples. Cards for equations, units and reaction types are usually the most useful, so keep them short and specific.

Frequently asked questions

How many flashcards should I make for a chemistry exam?

Aim for one card per definition, equation or reaction type in your notes. Single-idea cards are easier to review every day than long ones.

Is spaced repetition useful for chemistry exam review?

Yes, for most exam content. It shows you cards just before you would forget them, so nomenclature, units and formulas stick across the weeks before the test.

Can I export my chemistry flashcards to Anki or PDF?

Yes, on the Plus plan, which includes PDF, DOCX, Anki and CSV export. The free plan lets you study in the browser without exports.

Is there a free plan?

Yes. The free plan includes 3 generations per month and browser study, and you do not need a credit card to start.
