Its a Webinar using Cisco Webex.
Comminication is by audio and / or the webex instant massager.
You can dial in with a local number (for America), or just use the Webex session.
Our instructor is taking us through a set of slides and then giving direction / help during the lab sessions.
Half the time is spent listening to the presentation and the other doing the various lab exercises. Pivotal has provided a version of STS that contains all the required projects.
During the labs you complete one of the STS projects to reinforce the previous presentation.
The course is based on Spring 4 - which is nice!
I would have preferred doing the course in a class room, but for me that would have involved the expense and horror
that is London.
