Need a refresher course for your SAS (Statistical Analysis System) skills? The Centers for Disease Control and Prevention (CDC) offers a free course that walks you through the basics. This particular training is placed in the context of STD surveillance and covers ten modules worth of information ranging from epi terms to data sets to general features of SAS. If you are like me (who barely survived biostats), then this might become a very valuable resource. :)
