Which means that an applicant wanting to turn up at a training organisation just to take the exams before buggering off to some Floridian PPL puppy farm will find things rather more protracted and expensive under EASA.
The option to do the exams before "buggering off to some Floridian PPL puppy farm" was only ever realistically open to UK residents anyway. After all, the Florida schools operate under the CAA and thus would only accept the exams that were done at another CAA-oversighted school. That means that you have to live in the UK, or travel to the UK to do the exams.
But honestly, "getting the exams out of the way" isn't all that important before you go to Florida. After all, the exams take about an hour each, so you can have them all done in a single day. Or spread over a few days, in the breaks in between the flights. Or wait for the inevitable rainy day. Even on a three week intensive course there is enough downtime to sit all seven exams.
What is paramount before going to Florida, is to have learned all the theory and prepared yourself for the exams thoroughly (e.g. with the confuser). You should be 100% ready to take the exams immediately upon arrival. And that doesn't change with the new regulations.
