Whether you're a high school student or just starting out with your college coursework, the free software community has provided a wide range of solutions to make life easier. Browsing the package repository of my Linux distribution led me to applications for everything from gene sequencing to particle physics, but there are a few real gems I think any student could benefit from, including math and chemistry tools such as TiLP, wxMaxima, Kalzium, Gnome Chemistry Utils, and OpenOffice.org Math.
