No, it's okay. The reason why you want to bring your League membership card is because most students may have joined the League since high school. Remind everyone to bring your League membership card for easy stamping. I remember that every year, the membership card must be stamped. Joining the league is really a matter of personal will and will not affect your study and life.
I am a college student. Although you may not be in the same university as me, on the issue of membership, universities all over the country must be the same.
I hope I can help you and adopt it ~
