Hi @Gualigee,
I would complete all the weekly challenges as a first step. I think this will be really hard certification and weekly challenges should be the main point of the preparation process.
Regarding the predictive tools I think you would need to explore those tools more on your own as I am not sure you will learn what is required during the weekly challenges.
Same goes for SQL tools.
I think in a future some new learning materials should be developed as I don't think there are enough materials out there that would allow to easily prepare for this challenge!
