I already applied EIKEN 2nd grade this month.
But I found maybe I can easily pass 2nd grade without waiting examination day. So I'll also vocabill for pre-1st grade with studying for 2nd grade, and try a examination called CASEC at the end of this month. CASEC is web-based examination. I can try CASEC at everytime, and know TOEIC score and a EIKEN level.
Then I can pass over 2nd grade on CASEC, I'll apply pre-1 grade on top of 2nd grade.
