Welcome to Rodrigo Arenas Catalán's course site.
This site was created to make it easier for students to approach the courses I teach. Each course has levels with exercises and tests that will be assigned as homework by the teacher throughout the class. Apart from these, each course has a book with audios that will be sent to each student before the beginning of the lessons. It also has a blog where you can access articles, notices and relevant information about the courses. To enroll in a course, simply go to "Sign-up" and choose the course that suits you best.
