Hey! Go to https://apply.kean.edu/Ellucian.ERecruiting.Web.External/Pages/Welcome.aspx and sign in.
On the top left, there are options such as: Log out, My Account, etc... Click Applications.
You should be able to see the application for Summer 1 2018. The status should say "completed" and there should be a column for decision. Under the decision, it said, "Decision made". I also had a column that said respond.
I'm attaching a screenshot of how it looks for me now. Once I accepted the offer, my "decision made" changed to accept and I no longer have a respond column.
I really hope this helps you! Good luck!
