Education @ Your Desk. A Live Webinar Class means that you will attend the class via the web using your computer. There are scheduled breaks for coffee and lunch. You use a microphone, headset, or your phone and are able to interact with the instructor and other students while following notes while watching the presentation slides online just as you would in a live classroom. Notes are posted online. For an extra cost a hard copy can be requested.

The virtual classroom is becoming more and more popular, and we have a lot of experience teaching in this format. The only real difference between a live in-class and live via webinar is where you sit and what you look at. You can learn from the comfort of your own home or office. You pay less for the live webinar format than you would for the in-class format, and you do not have to travel to another city to attend the class. Please contact us at for Special Group & Corporate Rates for one or more participants.
