Ummm ... but according to their website they do not run the course. They only show integrated training, not separate groundschool
There are courses available abroad, in other JAA nations and in the USA, though one or two of the latter have lost their approvals, others shut for other reasons and I don't know who is left. One caution: before you take English-language groundschool under a JAA authority approval other than the CAA compare the exam system to the UK. The language is the same, the exams may not be.
The CAA has made massive changes, including fleibility about how many exams to write in the first sitting, extra sittings (up from 3 to 4 attempts per subject, total sittings raised to 6) and removing from the question bank hundreds of questions that are incomprehensible, unanswerable, ambiguous or simply incorrect. The few problems left are known to the schools. It may be that these changes have not been made by other nations, ans the exams may be considerably more difficult.
The schools in the newest member states may also be in the condition of panic all the UK schools were in 3 years ago!
I am not saying you
will encounter these problems, it may be that others are as well-set as we are here. You
may have difficulties, so study the issue and go in with your eyes open. The expense is such that some effort to investigate visit a few likely places is essential.
