I have 11 weeks until I go off to the good old US of A to do my JAA PPL, what I need to know is, do you think it's possible for me to complete all seven ground exam's here before I go in the time that I have remaining
These exams are not nuclear physics and they often seem to get imbued with an aura that is not warranted. Read the books, buy the PPL confuser and do all the questions and you will be fine. It is definitely possible to get them all in the 11 weeks with spare time self-study, even with a young family.
I also think it's important not to confuse learning a subject thoroughly with passing exams. The two only have a limited amount in common. Trying to combine them too assiduously leads to disappointment on both counts. If you want to pass the exams before you go, concentrate on passing the exams. Then, learn the stuff more thoroughly and relevantly when you're out there flying.
This experience stems from 6 years of medical school, followed by a series of postgraduate exams.
