Spanish 3 (Camden)

Rodrigo is an engineer, native Spanish speaker with some experience translating, currently working on his master thesis in Computer Science.  He has worked as a math teacher for more than fifteen years in his home city and as an instructor in one of the most prestigious universities in his country for more than five years before coming to the United States. As a teacher, one of his concerns has been the correct use of the Spanish, since many university students in his country lack some skills to write and communicate professionally.
