To Create a Combination Set:
To combine and merge multiple sets, start from a set page and click on “Combine” under "More."
You will be directed to the “Combine Sets” page, where you can add more sets to your combination. Just click the plus sign next to each set you would like to combine. Note that you can add sets that you've created and sets in your classes and folders.
You then choose to "Create a set" from the multiple sets you have selected. This will create a new set on your dashboard.
You can also select a study mode if you'd like to just study your combination in one of the modes:
Just click the "Go" button to start studying your new combination set!
How do I delete a combination?
Right now, there isn't a way to delete a combination. We're working on it! But if you choose to "create set" instead of just combining them for a specific mode, you can delete it.
