haha, seen this come up a number of times. No, you don't have to of passed Air Law before going solo. However, some clubs do insist on it.
And to the other post. I have not done any of the exams so far. I felt that it would serve me better if I were to learn by doing the practical (actually navigating and actually doing RT) before doing the theory. I guess it comes down to the type of person. Whether they take information in better by reading from a book or actually doing it.
