Well I rather think it would take more than 6 months for distance learning realisticly, as the full-time students take 6 months and they study more than 25 hours a week (excluding home study). I would say that it depends how much you study every day or week, and also if you are prepared, I though it would be a walk in the park like university at the start, but it certainly wasn't. But after completing them all now I feel free. You also have to put in mind that you have to do the brush up classes everytime you go in for an exam. They only start on certain dates and need to be booked in advance.
