exams
for a JAA frozen atpl, under certain circumstances the UK allows people to waive the need for the ground school and write the exams on their own, sweden does not. If you are exempt and write here in the UK then you will have to do a UK CPL skills test. Once that is complete I would suggest doing the IR in sweden as it is much cheaper and they are not so anal about radio work as the brits.
I converted my canadian ATPL to the UK ATPL recently and I know some swedish guys that have done the same..
