For quite awhile, Calvin has had two separate Google domains: the "@students.calvin.edu" domain for students and the "@calvin.edu" domain for faculty/staff. Calvin is now "combining" the two by letting students login to the "@calvin.edu" domain, and then removing the "@students.calvin.edu" domain.
You will login with your firstname.lastname@example.org, which is your "new" calvin email address.
Then you should copy your files from the current "@students.calvin.edu" Google Drive into the "@calvin.edu" Google Drive. You may do this anytime (like right now) but the deadline is April 30, 2022. In May of 2022, the "@students.calvin.edu" Google domain will be shutdown and all its files will go away. Permanently deleted. Done & gone. It's over. No recovery. Don't even ask.
Move it or lose it! Why wait? Moving your files is pretty easy. Here is a link to a short video which shows you how to do it.
