When you start a homework set, you'll be able to choose your homework set size depending on the available time you have. But if you don't have a lot of time, you can still select a large homework set size, which you can start working on, and then come back to finish later!
You do not have to complete a homework set in one sitting, you can exit the set and return to it later on.
To exit a homework set, click the back arrow located in the upper left corner of the toolbar.
This will pause the homework. Click Quit to exit the homework set.
When you exit a homework set the timer will pause and you will be returned to the homework page.
You can come back to this page to Resume any incomplete homework sets, later on.
The Progress Bar on the Homework Overview page will also remind you which lessons have unfinished homework to come back to!
