Thank you for viewing. It appears this product is being resold at a high price. This product is only sold on Mercari and Rakuma, and the price is basically 2000 yen, so please be careful of high-priced sales. Many people, including parents and children, are starting to study for the national flag certification, either for the certification itself or as a hobby. There are no past questions for the national flag certification, so it's unclear what kind of questions will be asked. However, I, who have taken the National Flag Certification levels 5, 4, 3, 2, and 1 and successfully passed all levels from 5 to 1 on the first try, have created mock exam questions based on the actual questions asked during the certification. The rules of the actual exam are also included, so you might want to try solving the problems while following the rules. Also, the number of questions is 100, and it is based on those taking the 1st grade, but the content of the questions also includes questions from the 5th to 2nd grades, so you might want to try it as a test of your skills. Since you are paying a high price to take the exam, please use this if you want to get as close to passing as possible. (Please note that this does not guarantee a 100% pass. Also, some editing has been added, and the number of pages has been reduced from before, but the content has not changed.) *There are also changes to the national flags, so I will correct them as soon as I notice them. Therefore, there are some changes from the content you purchased before, but please understand that national flags are always subject to change.
