Straight to the questions

Practise any university mathematics course

Each set generates unlimited questions by unit, with a worked answer after every one.

Build knowledge in a dependable order

University mathematics connects computation to models, proof, abstraction, and careful statements of conditions.

  1. Check the prerequisite

    Review the definitions and earlier results that the course assumes before starting a proof or calculation.

  2. Learn the central relationship

    A definition names the objects; a theorem or formula explains how those objects are connected.

  3. Use more than one representation

    Words, symbols, tables, graphs, diagrams, data, and code can show the same mathematical idea from different sides.

  4. Test independent recall

    Practice and course tests show whether you can select, complete, and verify a method without copying an example.

Before you start

Common questions

What maths do I need before starting Calculus I?

Comfort with algebra and functions matters more than any calculus preview: factoring, exponent and log rules, and reading a function's domain. Most people who struggle with Calculus I are struggling with the algebra inside the calculus.

Is university maths just harder school maths?

It is a different task. School maths mostly asks you to execute a method; university maths asks you to justify why the method is allowed, which is why proof and conditions matter so much more.

Which course covers proofs?

Discrete Mathematics introduces proof techniques directly, and Real Analysis and Abstract Algebra assume you can already write one. Start with Discrete Mathematics if proof is new to you.
