After the biology section, there is a prompt that asks if you want your test to be scored. Don't think there is a timer for this part, because I sat there for awhile trying to decide if my VR and WS was a complete disaster or not. In the end, I didn't want to take the god-forsaken test again so I clicked yes and went on my miserable way.
Also, at my test site I couldn't officially leave until I clicked "End" on my computer. So your proctors must have checked this with you before you left?
