I'm also in "application under review" but nothing showed up on "Admissions Requirements" page. I sent the admissions office an email asking for an explanation.
So I got my email today, and the website says that they haven't received my Part II yet. Even though I got the little card in the mail that says that they've received it.
So a couple days ago, the website didn't say anything about recieved materials. However, today it shows that all my stuff has been recieved, so I suggest everyone who might be missing materials check again.
