To see more details about your project while it's fielding, click the "details" button that looks like a small graph:

From here you can see how many completes you have obtained, how many completes you have left, and how many people have abandoned or terminated out of the survey.  

You can also see the Actual Length of Interview (ALOI) vs. the estimated time entered when you set up the project (LOI).

You can also click the "Download CSV" button which will give you demographic information on everyone that has completed your survey.
