Como ya sabéis, hace ya varios cursos (2010-2011) nos embarcamos en una nueva aventura: una sección bilingüe en nuestro instituto. Con el ánimo de desarrollar al máximo nuestras capacidades, de mantenernos en las líneas de educación actuales y de formarnos de la mejor manera posible, se ha creado esta sección. Y para complementar todo esto, surge este blog.

As you know, several years ago (2010-2011) we started a new project in our high school: a bilingual section. With the aim of developping our capacities as much as possible, continuing with the current educational tendencies and be trained in the best way possible , this section has been created. Thus, to complement everything mentioned before, this blog emerged.
