Application status help

so my account changed from ready for decision to pending student response. Does anyone know what that means?

It means the student has the option to be added to the wait list, and an email should be coming from the admissions office.

My account just changed as well from “ready for decision” to "pending student response as well! My major is animal health science. Does anyone know if I have to do something on my end or do I just wait for an email?
