Many thanks for the input, mate - I very much appreciate it. It's extremely helpful getting a more objective viewpoint on bootcamps, since the majority of information out there is from alumni and will always be positive.

My degree was faiyly comprehensive, it's just that since I graduated I have become pretty rusty on the fundamentals, but I guess that's something that should come back to me with a bit of revision.

I guess my main worry was the difficulty of finding a job in a new country with no prior connections and no real professional experience, but I guess I've got around a year to make myself marketable and attempt to build up a few connections from across the pond (maybe I can find a few Rails OS projects willing to take on an eager learner).

Thanks again!
