Hi Aidan,

What helped me was, thinking of a Process i want to implement and try it on a Test Database.
Odoo is pretty straight forward, as long you are tech interested.

What helped my personally a lot was watching a lot of youtube videos for specific topics. Like Project.
Also this forum can help with more specific questions.

But for the start its really best to invest 1-2 Weeks into the Leaning with the Videos, and do it beside.
Most of the time you need to have your Odoo open anyways to answer the Quiz Questions.

I can talk from personal Experiance, implemented Odoo for the Service department in a small company.
(we were just 2 People) The current account is new, and i need to go trought the Learning Video's again. But its a good refresher, and i don't remember everything.
