Please see the pdf file to the right for additional advice if you are unable to logon to Moodle from home.
I have been testing students logons from home and have been successful as have many other students from the looks of the access logs.
If you having problems maybe speak to a fellow student who has been able to logon successfully for advice or refer this to your ICT teacher or the ICT helpdesk.
Maybe see if you can test your logon on a friends PC who has logged on without issue (please do not divulge your password information to anyone).
