How a chemistry homework quiz helps you study

Stuck on a problem set the night before it is due? A chemistry homework quiz built from your own notes lets you test the stoichiometry, bonding and equilibrium material your worksheet covers without rereading the whole chapter. Upload the PDF or a photo of the page and the questions come from that exact material.

  • Multiple choice, true/false and short answer questions
  • Explanations that show the reasoning behind each answer
  • Works with PDFs, DOCX, PPTX, plain-text notes and photos of pages
  • Free plan includes 3 generations per month, with no credit card needed
Example chemistry homework quiz questions
What is the molar mass of CO2 using C = 12.0 and O = 16.0 g/mol?44.0 g/mol. One carbon (12.0) plus two oxygens (2 × 16.0 = 32.0) gives 44.0.
True or false: adding a catalyst shifts the position of an equilibrium.False. A catalyst speeds up the forward and reverse reactions equally, so equilibrium is reached sooner but its position does not change.
What is the pH of a 0.001 M HCl solution?3. HCl is a strong acid, so [H+] = 0.001 M and pH = −log(0.001) = 3.
What type of bond forms between sodium and chlorine in NaCl?An ionic bond. Sodium transfers an electron to chlorine, and the resulting Na+ and Cl− ions attract each other electrostatically.
How many moles of NaCl form from 2 moles of Na reacting with excess Cl2?2 moles. The balanced equation 2Na + Cl2 → 2NaCl gives a 1:1 mole ratio of Na to NaCl.

Questions from your own material

Upload a PDF, slide deck, DOCX, plain-text notes or a photo of a worksheet page, and get multiple-choice, true/false or short answer questions drawn from it.

Explanations for every answer

Each question comes with a short explanation, so a wrong answer shows you why the right one works instead of just marking it wrong.

Study in the browser

The free plan includes 3 generations a month and browser study. PDF and DOCX exports are available on paid plans.

How it works

Upload your homework or notes

Add the worksheet, lecture slides or chapter notes you need to review.

Pick a question type

Choose multiple choice, true/false or short answer, then generate the quiz.

Work through it and check explanations

Answer each question, read the explanation, and go back to anything you missed.

Quizzing yourself is more effective than rereading, and short questions with explanations show which steps you still need to practice. Mixing question types, such as a true/false claim about reaction rates followed by a multiple-choice calculation, helps you tell whether you understand the idea or only recognize the wording.

Frequently asked questions

How do I study for a chemistry test using practice questions?

Work through a set of mixed questions, then redo the ones you missed without looking at the explanation first. Come back to the weak topics a day or two later to check that the material has stuck.

How many practice problems should I do per chemistry topic?

Start with about 10 questions on a topic and add more if you are still missing them. Focus on the types your worksheet emphasizes, such as mole calculations or balancing equations.

Can I export the quiz to a file?

PDF and DOCX exports are included with the Plus plan at $39/year or $7.99/month. QTI 2.1 and Moodle XML export are available on the Pro plan at $14.99/month.

Is there a free plan?

Yes. The free plan gives you 3 generations per month and lets you study in the browser, with no credit card needed to start. Students get 40% off with a school email.
