Hello. I am writing to get soem opinions about SAC. I think that they are realy useful because students can get extra practice after classes. The problem that I face here in Mexico is that most of my students are not interesten in getting extra practice due to they are at university and they only wnat to get a document to get the degree. So they only try to pass the exam. About elementary school. Most parents do not speak English and say that it is not realy important that a child learn a second language.
