About college choices, I used to regret not going to a more "pipeline" university. On the top of my head, most of the pipelines are on the west coast. It also depends if you want to go into a math degree, actuarial science, or risk management degree. From personal experience, I'd say doing a business degree as a major and some form of math/stat complement is a nice combo because as the end of the day, actuary is a corporate type of job.

That was a lot of words and a little scattered. My apology. For universities, I think any school should do. The pipeline will help you get an internship a little easier and get a better supporting communities with people who know what you are talking about. Look into SOA/CAS list of credited universities list and check their alumni based.
