I am studying by modular and it has its moments. I have met a few DL students through electives and have always been impressed at how they can stay motivated and focussed and I am not sure I would have had the same level of dedication.I remember thinking the same thing (a your question) when I started and being annoyed by answers like mine but it is as 'hard' as you make it. The trick is getting the balance right. You very quickly work out how much effort is required for the mark you want to achieve and you can then work to that level.It is a great course, I have found it incredibly useful in a number of situations and would recommend it highly to anyone.The key thing to remember is that you can pick up subjects as full time on-campus modules if you want a break from the solitary book work. Good luck!
