Hiya!
When I last spoke to the GDC, they said its not necessary to re-take exams, once you are qualified, that's it. However, you do need to update you core CPD to bring yourself back up to speed with the current regulations etc. If you call them and speak to them they will be more than happy to guide you in terms of exactly what steps to take. The packages on offer on this website are quite good, all the nurses at my practice use them for our CPD.
