Starting University Advice Repository

I know quite a few (12+) rationalists and CFAR graduates who are entering University soon or have just recently started University.

There was a lot of advice I wish I had been given or heard before I entered University and I think having a good repository of rationalist-contributed knowledge/​advice/​suggestions/​information/​links/​DireWarnings could be very helpful to people in that situation.

1. What advice do students starting University need to hear?

2. What advice did your past self need to hear or what advice would have benefited you at that point in time?

3. Many people fail to ask the right questions. What questions do students need to ask themselves and other people?

Any links or guides on any related topics would be helpful. I will be posting some of my own ideas and links in the comments.
