Hi Bondgirl,
I will tell you the details here in case it helps anyone else too.
All the information you need is here:
http://www.londoninternational.ac.uk/
I dont know how it works for other courses but for Philosophy I applied, was accepted, and paid my registration fee etc last year around May. The relevant dates for applying and registering for courses are individual to the course - so check the website for whatever you are interested in.
Then in September I was sent some books, booklets, coursework guides, access to their online library, past exam papers etc..
In January I applied for exams - to sit in a Dublin exam centre so I had to apply to them as well.
I studied away at my own pace using the material sent to me, the internet, books and in may I sat 2 exams. I got my results in August and around 3 weeks ago sent off my re-registration fee and am now on my way for the next 2 exams.
Im actually doing the Diploma first, I did it that way in case I didnt enjoy it I wouldnt have committed too many years to it - but as it happens I like it so will definitely be going on to do the Degree.
Have a look on their website and see what you think. At this stage I think youd be looking at registering for the academic year 2011/2012 - and that may not suit you.
You should also take a look at Open University.
Feel free to pm me if you like, or ask me anything on here.
