Practising Higher chemistry with questions from your own notes

Most Higher chemistry revision comes down to answering questions under exam conditions, and a Higher chemistry quiz built from your own class notes lets you practise exactly what your teacher covered. Upload the PDF, slides or photos of your notebook, and DeckOwl writes questions with an explanation for each answer.

  • Questions drawn only from the material you upload
  • Explanations that show the working for calculations
  • Flashcards from the same notes with spaced repetition
  • Study in the browser on the Free plan, with exports on paid plans
Example Higher chemistry quiz questions
A compound contains 40% carbon, 6.7% hydrogen and 53.3% oxygen by mass. What is its empirical formula?CH2O. Divide each percentage by the relative atomic mass to get a ratio of about 3.3 : 6.7 : 3.3, which simplifies to 1 : 2 : 1.
What is the relative formula mass of carbon dioxide, CO2?44. Add the relative atomic masses of the atoms in the formula, so C 12 plus two O at 16 each gives 44.
True or false: raising the temperature of a reaction increases the rate because particles collide more often.Partly true, but the key reason is that more collisions have enough energy to reach the activation energy, so a higher proportion of collisions are successful.
Why does the pH of a strong acid rise by one unit when it is diluted tenfold?The hydrogen ion concentration falls tenfold, and pH is the negative logarithm of that concentration, so each tenfold drop adds one unit.
What type of bonding holds the particles together in a metal, and why does it conduct electricity?Metallic bonding, a lattice of positive ions surrounded by delocalised electrons. The mobile electrons carry charge through the metal.

Three question types

Multiple choice, true/false and open questions, so you can test recall, catch misconceptions and practise writing full answers.

Explanations for every answer

Each question comes with an explanation, so a wrong answer shows you the reasoning behind the correct one.

Export when you need it

Study in the browser on the Free plan. Export to PDF or DOCX on Plus, and to QTI 2.1 or Moodle XML on Pro.

How it works

Upload your material

Add a PDF, DOCX, PPTX, text notes or a photo of a page from your notebook.

Choose question types

Pick multiple choice, true/false or open questions, then generate your quiz from your own content.

Answer and review

Work through each question, read the explanation, and return to the ones you missed.

Because every question comes with an explanation, a wrong answer becomes a lesson rather than a guess. Multiple choice checks recall of definitions, true/false catches common misconceptions, and open questions give you practice explaining your reasoning in full sentences.

Frequently asked questions

How should I use practice quizzes when revising Higher chemistry?

Work through a set of questions across all topics first, then return to the ones you got wrong after a gap. Spacing your practice over several weeks tends to work better than one long cramming session.

Which Higher chemistry topics should I quiz first?

Start with the topics you find hardest, such as mole calculations and equilibrium, since later topics often reuse those skills. Quizzing on calculations early helps you spot gaps before they affect other units.

Can I export my chemistry quiz?

Exporting to PDF or DOCX is included in the Plus plan, which also gives unlimited generations. QTI 2.1 and Moodle XML export are available on the Pro plan.

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

Yes, the Free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start. Students get 40% off with a school email.
