# How can I solve the Sets task type?

## If you are struggling with solving differnet task types, we're happy to help you with some practical descriptions. Here you can find the steps of how to solve a Set task.

When sorting into sets, the cards in the middle must be sorted into the appropriate category. To start sorting the cards, click on the first card and drag it to the right set (don't let go of the card until it touches the set). If you want to undo a step, do it with the _Undo previous step_ button. You also have the option to check and modify all the elements in the set. To do this, click on the relevant set, which will display the items in it, with an undo button next to each item. Undo will move the card back to the centre, outside the set, from where you can reorganise it. If you want to know how many cards you have in line to categorize, check it in the upper right corner of a card.
