Do I have to take the whole certification test again?
No! The recertification tests only cover what has changed in QBO. You do not need to relearn anything you were tested on in the past.
How long is the test?
There are 2 sections for the Basic level and 1 additional section for the Advanced level. There are 10-12 questions in each section.
I just got my Advanced certification. Do I need to recertify my Basic?
You only need to recertify at your highest level.
