If your class occurs every other week, follow these steps. Currently, there is not a repeat every other day of the week option for class scheduling. However, these steps achieve the same results!
From the main navigation menu select Classes
Select a class tile
Choose the Schedule Tab
Select Add Schedule
Choose a start date and choose an end date*
Select the day of the week the class takes place
Choose Weekly under the Repeat drop-down
Fill out the details and select Save
*You will want to choose an end date because you will delete every other class instance
From the Schedule Tab select the first class day when the class does not occur
Choose Delete for the specific instance. An example of an instance would be Tuesday, Jun 20
Choose Yes, delete this class
Repeat this every other day of the week until your scheduled end date so your class is scheduled every other day of the week
