Why a math quiz should come from your own material

Most math practice sites work from their own problem sets, which rarely match the chapter your class covers this week. A math quiz website is more useful when it builds questions from your own material, so a quiz on quadratic equations uses your lecture notes instead of generic examples.

  • Questions drawn from your own chapters and lecture notes
  • Explanations that show each algebra or geometry step
  • Retry missed problems as flashcards with spaced repetition
  • Free plan to try it with 3 generations a month
Example algebra and geometry math quiz questions
Solve 2x + 7 = 19.x = 6. Subtract 7 from both sides to get 2x = 12, then divide by 2.
True or false: the derivative of sin(x) is cos(x).True. The derivative of sine is cosine, a standard result you can check from the limit definition.
What is 35% of 240?84. Percent means per hundred, so multiply 240 by 0.35.
Factor x² − 5x + 6.(x − 2)(x − 3). The two numbers multiply to 6 and add to −5.
What is the sum of the interior angles of a hexagon?720 degrees. Use (n − 2) × 180 with n = 6.

Built from your material

Upload PDF, DOCX, PPTX, plain text or photos of pages. Questions come from the chapter you are studying, not a generic problem bank.

Explanations for every answer

Each question includes an explanation, so a wrong pick on a percent or factoring problem shows you which step went wrong.

Review with spaced repetition

Missed questions can be turned into flashcards that return at increasing intervals, so algebra rules stick before the exam.

How it works

Upload your notes

Add a PDF, slide deck, text file or photo of a worked problem set.

Frequently asked questions

How many questions should a math quiz have?

Most practice quizzes work well at 10 to 20 questions, enough to cover one section without making the session feel long. A set of five is better for a daily warm-up on a single skill.

How should I study math quizzes to get the most from them?

Work each question on paper before you look at the choices, then read the explanation even when you got it right. Retry missed problems after a day or two so the method sticks.

Is the free plan enough to try it?

The free plan includes 3 generations per month and studying in the browser, with no credit card needed to start. Exporting requires Plus or Pro.

Can I export a math quiz to my learning management system?

Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML for importing into a learning system. Students with a school email get 40% off.
