What is the woman’s reply?

M: Has Professor Arnold from Sydney University arrived?
W: I’ll have to check. Then I’ll get back to you straightway.

W: You look exhausted this morning, Steve.
M: I am pretty tired. I stayed up nearly all night getting ready for a mid-term exam this morning.
W: Have you gotten the result of the test yet?
M: Yes, and unfortunately, my grade could have been much better.
