You don't need any app or programme to take the training course.
We use GoToWebinar to present the course which allows us to use video and power point presentation to present the training course, this is similar to Skype but GoToWebinar allows us to record a copy of each lesson so students can repeat the lesson.
We can answer questions live throughout the lesson.
We also provide a manual, a training site, a private Facebook page and back up and support.
