After each class, the teachers will upload the recording of the class video into a private Dropbox file. The link to the file of each group will be easily seen in your group whatsapp in the subject link (just under the name of the group). You can click on the link to access the file. If you do not have Dropbox, you can easily download it here. Dropbox is a free file sharing and storage service – by downloading the video you can rewatch your classes.
