You must now REGISTER

PAUSE A SESSION – to save an existing session, you will need to register. These details are not kept, other than to recognise where you left the session so you can resume at a later date from the same point as a Returning User. If you do not register, you will need to start the training from the beginning when you next log in.

PROCESS CERTIFICATE – to create a completion certificate you will need to register. This will then generate a personalised PDF that you can save to your documents. If you have already registered when pausing a session, your details will be used from that registration.
