The turnaround time is based on the teacher's schedule and how busy they are at any given time, as well as the volume of videos they have waiting for review. You can get an idea of how often they respond by looking at dates on the recent Video Exchanges.
As long as you see the VE Status as Pending, your video is still waiting for your teacher to review. If you have any questions please contact us and we'll be happy to confirm if your video was submitted successfully.
