I remember going through a phase of frustration concerning the weather (apart from waiting to go on first solo). All the solo navigation exercises I had to do (out the zone, north trip and south trip) were canned so many times due to the weather it was unbelievable. However, I think it has been balanced out, in the relatively quick time I completed the QXC and for the fact that I completed the skill test first time without having to weather it off! I think all the bad luck with the weather will balance out in the end, so don't worry, when you qualify, I am sure you will be as ecstatic as I am now
