Why a custom chemistry quiz beats a downloaded one

A ready-made quiz from one instructor, such as a Dr. Doe chemistry quiz, only helps if it matches the topics your course covers, and DeckOwl does not have access to any instructor's files. What it can do is turn the material your class uses into a quiz you can take on a phone browser. Upload your lecture slides, PDF handouts or typed notes and you get multiple-choice, true/false or open questions, each with an explanation.

  • Questions come from the slides and notes you upload, not a generic question bank.
  • Each answer includes an explanation you can read right after you respond.
  • The Free plan gives 3 generations per month and lets you study in the browser.
  • Plus adds unlimited generations and PDF, DOCX, Anki and CSV export.
Example general chemistry quiz questions
What is the pH of a neutral aqueous solution at 25 °C?7. Neutral water has equal hydrogen and hydroxide ion concentrations, so its pH is 7.
True or false: adding a catalyst changes the equilibrium constant of a reaction.False. A catalyst speeds up the forward and reverse reactions equally, so K stays the same.
How many moles of NaCl are in 58.44 g of NaCl?1 mol. The molar mass of NaCl is about 58.44 g/mol, so mass divided by molar mass gives 1.
Which quantum number describes the shape of an orbital?The azimuthal quantum number l. It sets the orbital shape, with l = 0 for s, 1 for p and 2 for d.
What type of bond forms when atoms share electron pairs?A covalent bond. Atoms share electrons instead of transferring them, which is what distinguishes it from an ionic bond.

Questions from your material

Upload PDF, DOCX, PPTX, plain text or a photo of a page, and get questions built from what your class actually covers.

Explanations for every answer

Multiple-choice, true/false and short-answer questions each come with an explanation, so wrong answers become lessons.

Export when you need it

Plus adds PDF, DOCX, Anki and CSV export, so you can print a practice sheet or move cards into another app.

How it works

Upload your chemistry notes

Add your slides, handouts or typed notes for the chapter you are studying.

Choose a question type

Pick multiple-choice, true/false or open questions, then generate the quiz.

Study and review

Take the quiz in your browser, read the explanations, and retry the questions you missed.

Chemistry rewards repetition. Use the quiz to check definitions, unit conversions and reaction types before an exam, then review the explanations for anything you got wrong. On Plus, spaced repetition brings missed questions back at the right time so they stick.

Frequently asked questions

How many quiz questions should I make from one chemistry chapter?

Start with 10 to 20 questions per chapter, covering definitions, formulas and worked problems. Generate more after you finish a unit so the quiz covers the whole topic.

What is the best way to study chemistry quiz questions?

Answer each question before you look at the notes, then read the explanation for every miss. Retake the missed questions a day or two later to check that they stuck.

Can I print my chemistry quiz?

PDF and DOCX export are part of Plus, which costs $39/year or $7.99/month. The Free plan lets you take the quiz in your browser without exports.

Can I study on my phone?

Yes, DeckOwl runs in a web browser, so you can take quizzes on a phone. Exports such as Anki and CSV require Plus.
