Hi @dkwlsWK — welcome! We don't currently offer support in Korean on Figma Forum, so I hope it's okay that I'm replying in English.
Sorry to hear you’ve run into a roadblock with this, and for the disruption with your assignments.
If you're enrolled at a higher education institution, SheerID is the team to reach out to. They handle verification for higher education students and can reset your verification attempts. You can reach them at: figmasupport@sheerid.com. It helps to include the school email you're verifying with, a screenshot of the error if you have one, and a short timeline of what you've already submitted.
If you're in high school or a bootcamp, the process is different. You can find details here: Figma for Education → Verify your education status.
If any questions remain, reply here with more details and I'll take another look. 🙏🏻
