There are no rules or regulations about this.
The course is supposed to consist of 750 hours of studying. If you do a distance learning course, you can study at whatever speed you want. If you really feel that you could study for 10 hours a day, 7 days a week, then this works out at just over two months.
Add another two weeks for actually doing the exams (assuming you do them in two blocks, as recommended by most schools). Add a bit more, because the brush-up is a mandatory part of the course and it won't be 10 hours a day 7 days a week (although once you add on the time you spend doing brush-up papers, it's not far short!) and it should be possible to have it all done in 3 months. In theory.
In practice, I would be very surprised to hear of people who have done it that quickly. I know my concentration span isn't good enough to study that intensively, I don't know about you.
