Here it goes a useful Youtube video that proposes a simple how-to-instruction of Google Drive and Google Docs which I consider very useful when working online with somebody else.
My advice is that if you want to get organised within the 'net', I fully recommend that you choose all applications that come from Google, namely Google Drive or Docs among many others. Nowadays, the company provides many applications and widgets that are really helpful for students and teachers. For instance, you count with an online calendar in which you can create new events, and if you run the possibility of having a smartphone with Android (Google Operating System), Google coordinates this online calendar with that of your mobile and delivers a message whenever a programmed event is near.
For teacher, this applications, and many others, can be of fantastic help and time-saving.
