You can enrol anytime but will receive a programme of study based on a September start date to help you keep on track.
Delivery is through video lessons, live drop in classrooms, class notes, self assessment, home practicals, tutor marked assignments and exam practice.
You can work through the programme at your own pace and start as soon as you enroll.  You can attend any timetabled drop in sessions on your enrolled programme.   The programme of study is based around a typical academic year so there will be holidays timetabled, but, again you can choice to continue through these holidays or take holidays at other times if you wish.
Once enrolled you will receive access to moodle for that programme.  All materials are there.  Moodle is a learning management system used by schools and universities all over the world.
In addition to all of the above you will access to tutor support via email.
Visit the individual programme pages for more details and to see an example programme of study.
