The homework assignments and updates will be sent to you as email attachments after each class.

There are many Excel resources on the internet. A free online tutorial by the Baycon group which is designed specifically for beginners can be found at Baycon Tutorial. Another helpful tutorial offered by Florida Gulf Coast University can be found at Excel 2007 Tutorial.

Please note that while the online tutorials make very handy references, our class topics and assignments will not track these tutorials exactly.
