Day Skipper course/exam doesn't teach you to handle any specific conditions - it teaches the basics and also teaches you to assess the conditions and whether or not you, your craft and your crew will be capable of coping with them (at least it's supposed to). The trouble is you can usually gradually work up to more extreme weather conditions, etc. (with the odd grey hair moment along they way). If you've passed a course in the Med though you could be a very competent sailor experienced with some very nasty seas and winds, able to cope with Med moors, etc. and then come over to Poole Harbour. You then go out on a glorious sunny day in a F3 and quickly get added to the list of people that have ended up under the chain ferry.
Likewise you could spend a week in perfect weather on the south coast perfecting your ferry glide and then head out to the Med and get bounced off every boat in the harbour by katabatic winds
Hopefully a responsible person interested in getting the best out of the course, rather than just a piece of paper, would (or should) choose to do it in the waters they will do most of their boating in. They can then get a broad knowledge and some practical experience of specific skills applicable to them and made aware that if they ever go somewhere else they may encounter things they have not experienced...
