I didn't check, but I think this might be my fault (don't remember how I phrased it). Just to clarify any earlier statements, Alex is right, you can learn with the book, and many people have. But it seems to be the general consensus here that the course is easier (but still requires practice) and that the live seminar has the highest success rate.
In your case, Marcus, I would suggest coming to the forum often with any questions you might have.
Don't worry, with enough practice, I'm sure you'll get it =)
