So exact time in this ward only 6 weeks, I told school whether can I have another three weeks to go, however head nursing said I already finished 276 hours in training and the maximum time is 300 hours, I seriously don't know what should I do, feel lonely hopeless, end of the world, spent a lot of money gathering all documentation backwards forewords from my country to council, now suddenly I hit the brick wall, does anyone know any solutions, pls give me some feasible advices. How can I having a chance for another three weeks which looks like impossible rejected by school through the phone conversation,
