Can I save a lesson after doing some of the exercises and come back to complete it? At the moment it seems that I have either to complete the whole lesson or come back and start from the beginning again.
You can pause the lesson in Exercise settings by de-activating the automatic question option. Then you can take a break and continue where you stopped.
But you can't close EarMaster and carry on with an unfinished lesson later I'm afraid.
Let me suggest that the ability to save a lesson at whatever point one is at, close Earmaster, and come back to it later would be a great, and I would argue, almost necessary feature to add to this fine software.
