I completed the ATPL(H)/(A) bridging exam in 2005, I was, I believe, the first to do it and the support from Alex and his team was excellent. (thanks again Alex
)
If you can get in on the current 'interim' arrangements then go for it, the exam, as I remember it, was fairly easy with the right prep and took me a total of 15 minutes to complete with a score of 96%!
