EnglishWhat math courses and test prep does Mathplanet offer?
Updated
Mathplanet offers four core high school math courses — Pre-Algebra, Algebra 1, Algebra 2, and Geometry — plus SAT prep and ACT prep with practice tests and tips. It also lists Math Playground, Programming in Python, and practice tests as additional tools. The site describes all of this as completely free, and it is run by Mattecentrum, a non-profit organization founded in Sweden.
Core high school math courses
The four main courses are organized by level and topic:
| Course | Focus |
|---|---|
| Pre-Algebra | Building your foundation |
| Algebra 1 | Equations and functions |
| Algebra 2 | Advanced algebra topics |
| Geometry | Shapes, proofs, and space |
Each course has its own "Start course" entry point, so you can begin at the level that matches your current knowledge rather than working through everything in sequence.
Test prep: SAT and ACT
Mathplanet provides dedicated prep sections for two standardized tests:
- SAT prep — practice tests and tips, with a "Start practicing" entry point.
- ACT prep — practice tests and tips, also with a "Start practicing" entry point.
If your goal is college admissions testing rather than course study, these two sections are the relevant starting points.
Additional tools
Beyond the core courses and test prep, the site lists:
- Math Playground
- Programming in Python
- Practice tests
These sit alongside the main curriculum as supplementary resources.
Who it's for and how it's funded
Mathplanet is a free service from Mattecentrum, a non-profit founded in Sweden. The site states that over 300,000 people learned math there for free in a year, and it asks for donations to keep the service free. If you want structured high school math coverage or SAT/ACT practice without paying, this is the intended audience. If you need something outside Pre-Algebra through Geometry, advanced college-level topics, or a specific national curriculum, the listed courses may not cover it.
