DL
Hi Andy20,
I've just finished a course that included ATPL study DL. I found it hard but once you stick with it you'll get through it fine. The other thing that I would suggest is to check to make sure that the necessary support is in place in case you need it. In my situation the support was minimal at best, but there is a lot of information on the internet that did help. Also if you know someone else that is also doing them via DL then it's a good idea to stay in touch as there maybe something that they can help you with and vice-versa.
If I had to do it all over again I would look to an organisation that has proper support or would think about doing it in a class room with an instructor. As I said it was difficult but through stubborn perseverance I managed to get through it.
Just my thoughts.
