What's Here

For each link at left you will find

• Video discussing the topic
• Practice questions
• Online slide show (Microsoft IE 5.0+ ONLY -- see notes below)
  
• PowerPoint presentation (no audio)

The idea is to go through the questions to see what you already know. Then look at the video to get a refresher course on the concepts involved. Finally, go through the questions to see how much you have retained.

Online Slide Show:

• This will show all the images at a larger scale than the video
• Click on sound icon at top right of slide to hear the commentary, or
• Click the Slide Show button (at right, below the slide) and audio will play automatically)
