Why generate your own hard math questions

Most ready-made banks are too easy or too generic for a specific course, so the fastest route to hard math quiz questions is to build them from your own material. Upload a PDF, slide deck or typed notes and DeckOwl writes questions that follow your chapter's actual methods and notation.

Example hard calculus and combinatorics questions with answers

Find the derivative of f(x) = x^x.f'(x) = x^x(ln x + 1). Logarithmic differentiation works because ln f = x ln x, so f'/f = ln x + 1.

How many real solutions does x^3 - 3x + 1 = 0 have?Three. The discriminant is 81, which is positive, so the cubic has three distinct real roots.

Evaluate the limit as x approaches 0 of (1 - cos x)/x^2.1/2. Using 1 - cos x = 2 sin^2(x/2) turns the ratio into (1/2)(sin(x/2)/(x/2))^2, which tends to 1/2.

How many distinct arrangements of the letters in MISSISSIPPI are there?34,650. Divide 11! by 4! times 4! times 2! because the repeated letters are indistinguishable.

True or false: every bounded monotone sequence of real numbers converges.True. The monotone convergence theorem guarantees that a bounded increasing or decreasing real sequence has a finite limit.

Generate the full set

Multiple-choice, true/false or open questions

Pick the format that fits your practice. Open questions make you write out each step, while multiple choice is quick for checking recall.

Explanations for every answer

Each question includes an explanation, so you can see exactly where a wrong method or a sign error went wrong.

Built from your own material

Questions come from the chapters, examples and problem sets you upload, so the difficulty matches your class.

How it works

Upload your material

Add a PDF, DOCX, slide deck, plain text notes or a photo of a worked page.

Choose the question type and count

Select multiple choice, true/false or open questions and generate a set for one topic or a whole unit.

Answer, read the explanations, and repeat

Work through the set in the browser, check each explanation, and regenerate on the weak topics.

Harder items usually test why a method works, not just the final number. Mix open questions with multiple choice so you have to write out each step, then read the explanation to find where your reasoning slipped.

Frequently asked questions

How many practice problems should I do for a hard math exam?

Work until you can solve new problems of the same type without looking at worked examples, which often takes several varied sets per topic. Mixing problem types in one session helps you practice choosing the right method.

What makes a math question hard?

Hard questions often combine two ideas, such as a limit and a derivative, or ask you to justify why a method works. Open-answer practice forces that full reasoning, which multiple choice can hide.

Can I export these questions to Moodle?

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

Is there a free plan?

Yes, the Free plan includes 3 generations per month and studying in the browser, but exports are not included.
