My daughter wants to go to senior high school. Its entrance examination will held next February. To prepare for the examination, my daughter will take several mock examinations (simulation tests) from September to January. The fee of the mock test is 4000 yen ($39.22 €29.20). My daughter is going to take them four times, so the total cost is 16,000 yen ($156.86 €116.79). After the mock exam, each time she will received the result and "deviation score" which is an index to measure the possibility to pass the entrance exam.
