DH may stand and read from the notes, but he knows exactly what you need to pass the radio exams. No more no less. The same with Law.
LGU is pretty good, the lectures are friendly and genrally more than willing to help. I was there full time, but often heard them talking about distance students they were helping via telephone and internet. They also have this great web link, that you will be given access to which will keep you in constant contact with the tutors.
I did find the notes a bit bland and lacking in certain subjects, in fact one subject didn't even look at the notes, but have heard that they have changes and updated their notes, following a simular pattern to the Jeppsen notes, so if that is true then you have nothing to lose really.
Best of luck, and remember no matter where you go it is going to be difficult, especially doing a DL cource, just keep at it, and find a school that will be there to help you when you need help.
