Topics
Social background Family income has been discovered as animportant factor for success. Does the data scientist’s work end here?
Study conditions How to measure and find aspects that counterbalance negative preconditions of the social background?
Health How does the mental and physical state influence success and failure?
Open Data What if Student Life Cycle Data were open?
