Disclaimer

LR Abacus Practice Test is a personal, non-commercial project. I built it to give my own son extra abacus practice, and I've made it free for any other family to use in the same way. There are no ads, no subscriptions, and no hidden costs, and there never will be.

I'm not a professional software company, and this site is maintained by one parent in their spare time, with the help of an AI coding assistant (Mr. Claude Code). While I do my best to keep every test question accurate and the site running smoothly, I can't guarantee it will always be error-free or available without interruption.

This site is a practice tool only - it's meant to complement, not replace, proper abacus classes or coaching. It is not affiliated with, endorsed by, or certified by any abacus institute, school, or examination board.

If you notice a wrong answer, a bug, or anything that looks off, I'd genuinely appreciate you letting me know via the Contact page - it helps make the site better for every child using it.
