Common questions
Who is "Algebra I" for?
It is written for learners at High School level (Grades 9–12), and for anyone older who wants a clear refresher on mathematics. Linear equations, inequalities, and functions — the core algebra every high schooler needs. There is no application or entry test — you can start the first lesson straight away.
How long does the course take?
There are 4 lessons totalling 33 minutes of reading and quizzes, laid out over 3 units. You can move at your own pace — progress is saved as you go.
What do I need to know before starting?
No prior coursework is assumed. The course opens with "Solving Linear Equations", covering isolating x and multi-step, so the foundations are built in rather than expected.
Is the course free?
Yes. Every course on Monster Class is completely free, with no credit card, trial period or paywall. Creating a free account simply saves your progress, XP and place on the leaderboard across devices.
