They aren't a scam, I was sceptical too but my experience has been so good. I got offers from all my choices including Kings college London and University of Birmingham to do nursing. The assignments are really straight forward and easy and the study materials cover everything well you need to know to answer the questions, and the recorded lectures are great as they tell you everything you need to write to get that distinction! I chose to study with them because I wanted to study at my own pace at home and I'm self motivated (you need to be, because you get very minimal communication from tutors except from sending a draft for assignments 1-9 and when you need to ask questions they take a while to respond but as you are starting it now you have a lot of time to get this done)
