Why a custom quiz beats a generic worksheet

Most class 11 chemistry syllabi cover atomic structure, the mole concept, chemical bonding and chemical equilibrium, and a class 11 chemistry quiz is most useful when it matches the exact chapter you are studying. Generic sets often test topics your teacher skipped and miss the ones they stressed.

Covers the chapter you are studying, not a generic syllabus
Multiple-choice, true/false and short-answer formats in one quiz

Example class 11 chemistry quiz questions

How many moles are in 36 g of water? (Molar mass of H2O is 18 g/mol.)2 mol. Moles equal mass divided by molar mass, so 36 ÷ 18 = 2.

True or false: isotopes of an element have different mass numbers.True. Isotopes share an atomic number but differ in neutron count, so their mass numbers differ.

What is the electron configuration of oxygen (atomic number 8)?1s2 2s2 2p4. Eight electrons fill the orbitals in this order, leaving four in the 2p subshell.

What is the geometry around carbon in methane (CH4) according to sp3 hybridization?Tetrahedral, with H-C-H bond angles of about 109.5°. The four sp3 orbitals point toward the corners of a tetrahedron.

For N2 + 3H2 ⇌ 2NH3, what happens to the equilibrium if pressure is increased?It shifts toward NH3. The forward reaction produces fewer gas moles (2 instead of 4), which relieves the added pressure.

Questions from your material

Each quiz is written from the pages you upload, so it follows your syllabus and your teacher's terminology.

Three question types

Choose multiple-choice, true/false or open short-answer questions, and mix them within one quiz.

Explanations for every answer

Each question comes with a short explanation of why the correct answer is right, so a wrong guess becomes a lesson.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a page. Photos are read with text recognition.

Pick the question types

Select multiple-choice, true/false or short answer, and set how many questions you want.

Take the quiz in your browser

Answer the questions, read the explanations, and review the ones you missed.

If you were hoping for a printable worksheet, DeckOwl takes a different route: it writes a quiz from the class notes, slides or PDF pages you upload. The questions use your teacher's wording, which makes them more useful before a unit test than a ready-made set.

Frequently asked questions

How many questions should a class 11 chemistry quiz have?

Around 10 to 20 questions is enough for a first pass through one chapter, and a unit test review may need more. Include some calculation problems, such as mole or molarity questions, alongside definition questions.

Which class 11 chemistry topics should I quiz myself on first?

Start with the mole concept and atomic structure, since stoichiometry and chemical bonding depend on them. Quiz yourself on each chapter before moving to the next one.

Can I export the quiz to PDF or Moodle?

PDF and DOCX export are included in the Plus plan at $99.90/year or $9.99/month. QTI 2.1 and Moodle XML export are on the Pro plan at $14.99/month.

Is there a free plan, and do I need a credit card?

The free plan gives 3 generations per month, and you can study in the browser without exports. No credit card is needed to start, and students get 40% off with a school email.
