I want to take the “Rank Up Test” but it says “Application Denied”. Why is that?

Only those who have passed the “Registration Test” can take the “Rank Up Test”.
Unless you have passed the “Registration Test”, the “Rank Up Test” will appear as “Application Denied” to you. So please take and pass the “Registration Test” first. Also, please note that you don’t have to pass both “Japanese to English” and “English to Japanese” Registration Test in order to be eligible for the subsequent “Rank Up Test”. So be sure to take the test that best suits your skills first. Even if you failed the test, you may retake it again after a certain amount of time has passed.
