Excerpts from website:

This site will help you:

1) learn accounting basics,
2) have an opportunity to solve accounting problems and strengthen your knowledge and skills, and
3) determine whether your solutions to problems are correct and, if needed, determine the reasons for mistakes (though, we hope you will do fine even on the hardest exercises).

We advise you to go through lessons first and then work on the problems. Solutions are provided for your reference. However, the best results can be achieved only by working on the problems before looking through solutions.
