How long did it take for the math placement test to say "completed" in tasks?

I just took the math placement test, and I’m concerned because it does not say that I completed it, although I understand that it does say that it takes up to two days for it to say “complete.” What I am worried about is that when I go to the site for the math placement test, it is allowing me to go back in as if I’m about to take the test. What I mean is that I can go to the “take test” page right before the test is about to be taken. Is this normal? It doesn’t say that for the sample test- for the sample test, it says that I already completed it. I don’t know what to do… should I be worried?
