Ecosystem: Great, Redrock: Bad experience
-Ecosystem videos: 10 out of 10 I enjoyed it, and learned a lot. the ecosystem game became so easy to solve. - Redrock videos: 3 out of 10 Bad experience. the videos lack a lot of information, Francesco only explained the game mechanics, user interface, and some basic tips here and there. (which by the way, all these will be explained in the untimed tutorial of the actual test). I learned almost nothing new from the Redrock videos, and it didn't prepare me to solve the real game at all. Ecosystem: 76+ minutes worth of informative content. Redrock: Only 30 minutes worth of repeated and uninformative content.
