This course consists of 6 instructor-led live sessions which consists of presentations, demonstrations and discussions of questions. During each session, participants can ask questions to the instructor (through chat or microphone) which will be answered. After each live session the recording of that session, used slides and exercise documents are made available to participants to view again. If desired by the instructor, exercise files are provided at the end of a session that will be discussed in the next session. These should be performed by the participant before they are discussed in the upcoming live session.

Access to the course
After your purchase is confirmed you receive an account to the EngineeringTrainer online learning portal, where you find the course welcome chapter and instructions on how to join the live sessions. Sessions are held using the software GoToMeeting and a log-in link is provided for each session through the portal. A test link is provided from the start such as to test if you are able to properly join the sessions prior to the first session. Live sessions can be joined using any device, including tabled and mobile.
