In Sweden , i would attempt a culinary apprenticeship considering continental europe doesnt really go by culinary schools, they have them, but its more of a hobby kind of institution.
Completing an apprencticeship will give you a diploma/certificate that will verify you are a cook and completed your apprenticeship.
Not only that but it can be more valuable on a resume.
The apprenticeship is an agreement made by the you , the restaurant and the goverment so you know its serious.
Im pretty sure other members ( mainly foodpump who gave me some info ) have more details.
Now if you actually want to go to a culinary school , their is one that has crossed my mine a few months ago , which is the Culinary Arts Academy of Switzerland , i dont know how good it is , but their was a Brazilian particpant in the Bocos D´or who graudtaed there.
He actually lives pretty close to me though i have never met him in person.

P.S. most who do apprenticeships start at 16 , but im sure you can do them even if you are older.
