Enroll in classes at a college level. Schools like the University of Pennsylvania offer Swedish at beginner and intermediate levels, giving you the opportunity to learn with others that are at a similar level of expertise.
Practice your Swedish via telecommunication. Online services like Livemocha give you free access to native Swedish speakers that can help you with your grammar, pronunciation and more.
Take non-credit language instruction classes to relieve some of the pressure of academic studies. The Swedish School in Virginia, for example, offers Saturday morning adult education classes to help adults learn Swedish.
Invest in language teaching software for your computer. These programs, which are often available in Swedish, allow you to learn a new language while moving at your own pace and in the comfort of your own home.
