I checked out their website and I find it a bit of a joke. First off, their Introduction to CS includes topics like PL/SQL which is proprietary. Oracle states that their Introduction to CS workshop is free and then when you go to enrol it is only available in China, India, and Brazil. I was expecting them to offer something like the FREE course that Stanford offered this spring by Nick Parlante.
"Few subjects will open as many doors for students in the 21st century
as computer science (CS). The Oracle Academy provides resources to
help awaken and deepen student interest in this important field of study."
