What is the best alternate WORD for "Bookmark" and "Save" feature of a mobile app?

I'm talking about an educational app, in which user learn different lessons if they want to quit or leave in middle or somewhere during a lesson, they save their current session/learning, so when they come back, this feature will remember them where they left in the previous session and proceed to continue their lesson. This feature isn't bookmark nor save, but functionality wise its like save.

There is no reply.
