<p>So I've been on medical leave for the past two years (it might end up being three). First I noticed I'd forgotten what a binomial distribution was. Then, all of special relativity. Now I'm petrified that I'll go back to college completely ignorant of everything I learned in high school (and freshman year). I've still got calculus under my belt and most of elementary linear algebra but I seem to have forgotten a lot of physics, chemistry &c. Once upon a time I was a competitive student with a strong background ... but now I'm not sure if I can muster the connections needed to solve difficult problems.</p>
<p>1) How important are scientific fundamentals for a math major?
2) Are they easy to pick up on the way, or will I flounder in my classes for lack of basic skills?
3) What can I do to review stuff quickly?
4) Nontraditional students - has this been a problem for you personally?</p>
<p>(For that matter, I've taken like one English class in the last three years. I hope I haven't forgotten how to write.)</p>
