The resource you want really depends on what you are trying to do and what program you are using. http://www.actionscript.org/resources/categories/Tutorials/ can probably get you started if you are using Flash or Flex.

Outside of that, if this is for exams, I’d suggest speaking with the professor. If you aren’t understanding something in a lecture, you should tell that to the professor so you can meet with him outside of class and get the help you need.
