Can I start the QBO certification test, stop and then resume the test?

I need to take the QBO certification test.
Does anyone. who has already taken the test, know if it has to be done all at once or if I can start, stop and then go back to it?
The test instructions don't say whether one has to finish it once it starts. It only says that each section has to be submitted at a time.

Hi,
The test saves your progress.
So, you can start it, then take a break and resume it when you’re ready.
Hope this is helpful.
