A Free Alternative to IXL for K-12
Unlimited practice in Math, English, Spanish, French, Computer Science and Life Skills — with worked-example tutorials and a diagnostic that builds a personalized plan. Free to start, no per-subject paywall.
Free to start · No card required · K-12
IXL is a great practice tool, but the cost adds up fast — memberships are billed per subject, per child, every year. For families and homeschoolers covering several subjects or kids, that quickly runs into hundreds of dollars.
ExcelOS takes a different approach. One free account unlocks practice across every subject and grade, K through 12. Instead of just marking answers right or wrong, ExcelOS runs a quick adaptive diagnostic, pinpoints exactly which earlier skills broke down, and builds a personalized learning path to fix them — the same "find the gap, then close it" idea, without the per-subject bill.
Every lesson includes a step-by-step worked-example tutorial before the practice questions, so students learn the method, not just drill it. Instant feedback and explanations come standard.
