Once you have booked a class, you can add the event to your Google Calendar. What you need for this is a confirmation e-mail of the scheduled activity. If this setting is not ticked in your settings then you can change this in Account Settings (see the steps for this in the paragraph below)`
Log into your online profile page via a laptop, PC or tablet > click on the arrow pointing down, next to your screen name > click on 'Account Settings' > click on Email settings > navigate to 'Groups and Challenges' > tick the box 'Class booking confirmation'.
When you book a class now, you will receive a confirmation in your mailbox. When you open the e-mail, click on 'Add to calendar' > click on 'Save'. The activity will now be added to your calendar.
