SchoolCam allows you to pick and choose the exact folder on your Google Drive where to save the photos and videos you take. We supported Shared Folders as well as Shared Google Drive.
If your school allows you to save to your personal drive you can use the ‘My Drive’ tab in the home screen like this:

In the camera view of the app you can also change the folder where your photos and videos are saved

Once you select the destination folder all new photos and videos you take will be automatically saved to that folder. Note that previously taken photos will be uploaded to the folder that was selected as destination folder when the photo was taken.
