I converted from FAA via Dragon. Was on one of the early (ish) courses and we had a few minor teething problems. As soon as anything came up problem wise. It was immediately addressed and rectified. The Chief GI is excellent and if you apply yourself,, you will pass...I have no knowledge about other schools. But I would be happy to do it again with Dragon. Or at least as happy as anyone could be, having to study this impractical syllabus.
I have struck up a friendship with the staff at Dragon, so my opinion is biased. I say this because all opinions are biased. And someone's inability to apply themselves and therefore fail. can't be attributed to the school.
You'll be hard pressed to find a more knowledgeable person than Dragons' CGI...And equally hard pressed to find any organization more willing to go the extra mile to get you thru something you don't quite get..
In addition, much has been said about Dragon from people with 4th hand knowledge. Kind of like a chain letter..read it and pass it on!
But of course it's a biased opinion
