# For example, is it possible to restrict the examination so that you cannot apply for Level 2 unless you have obtained Level 3?

## Purchase restrictions are possible with the custom badge function.

By using the custom badge function, you can set a restriction that only users (successful applicants) who have obtained a specific badge can purchase a specific product. For example, it is possible to set that only those who have purchased and passed the 3rd grade certification test can purchase the 2nd grade certification test, which is the higher grade, on the certification content sales site.

※You need to apply for this function in the [EC plan](https://learningbox.online/en/%E6%96%99%E9%87%91%E3%83%97%E3%83%A9%E3%83%B3/%E3%83%A9%E3%82%A4%E3%82%BB%E3%83%B3%E3%82%B9/ec%E7%89%B9%E5%88%A5%E3%83%A9%E3%82%A4%E3%82%BB%E3%83%B3%E3%82%B9/).
