Anything from general education about our world and universe to natural sciences and more. But most importantly scientific, critical and rational thinking. The more the better. The quality of the education is of utmost importance as well. Sadly education isn't given the importance it needs in most places today, it has only become a tool to teach you how to do certain jobs. Anything that's not directly related to ones profession is dismissed as unnecessary. I don't consider the majority of students to be much educated in the scientific way, and with people who haven't visited a school or university for ages this tends to be even worse.

Anyways, this trend is very noticable in all of our societies, and there is nothing suggesting it would suddenly change the higher you go. This is where the whole debate began.
