Question Explanations
We provide a detailed solution for each test question, including step-by-step calculations. By reviewing these solutions, you’ll not only learn which answer option is correct but also gain an understanding of why it’s correct. This approach ensures that you can apply that knowledge to future challenges.
Compare Your Score
To gain a better understanding of your performance level, you can compare your score with those of previous test-takers.
Additionally, during test review, you have the option to view how other users answered specific test questions. This can provide valuable insight into areas where you may need to improve or focus your study efforts.

Simulate the Real JOA
Practice under real JOA conditions with four full-length simulated tests.
Each of the four simulated tests includes 51 questions and a 20-minute time limit—just like the real JOA. The tests also reflect the same balance of question types found in the actual exam.
These questions have been carefully selected to replicate real test conditions as accurately as possible. Use the simulated tests to sharpen your time management skills and assess your performance level.
Study Tools
With the Mathematical Study Guide, you can study most of the basic mathematical theories required for the JOA, such as fractions, decimals, percentages, interest, and algebra.
Practice unlimited mental calculations with the Arithmetic Trainer.
