Questions
Who is this for?
Accounting and business students, new bookkeepers and staff accountants, and anyone who wants debits and credits to feel automatic. The entries follow US GAAP and standard textbook account names.
How is my entry checked?
It must balance, use the right accounts and put each amount on the right side. Line order does not matter, and splitting one account over two lines is fine. If something is off, you are told what kind of mistake it is without giving the answer away.
Do I need an account?
No. The first five exercises work without one and save progress in your browser. A free account saves progress across devices, and Pro unlocks the rest.
How do I cancel the monthly plan?
Open Account and choose Cancel subscription. That is the whole process: you keep Pro until the end of the period you paid for and are not charged again. If Pro is not for you, you get a full refund within 14 days of paying.
What if my answer is right but marked wrong?
Answers are checked on the result they produce, not on how they are written, so any correct answer passes. If a check still gets it wrong, use the report link under the result. Reports are reviewed, and a check that is wrong gets fixed.
