Thanks for your advice.
I know I could study the PPL at home but I get distracted very easily at the moment and I think travelling up one night a week might not hurt and hopefully I can get around the congestion charge problem...
I think I will go for it. This way i know for sure (well not for sure, sure!) that I will get these 7 exams over and done with as they've been playing on the back of my mind for a long time. At least it allows me to concentrate on the practical side of flying down at the club.
