Adobe TV has some of the best tutorials and videos so you can refresh your memory when you are out of class. We are using Adobe applications of the CS4 version (which are not the latest) so it is best to use the documentation and tutorials for CS4 because newer versions have different menus and functionality which might be confusing.
