There are a variety of language schools available that offer high to low-intensity courses. A high-intensity school would expect you to attend classes, complete a significant homework load plus also do a lot of self-study, meaning for the first three months of school they do not recommend, or in some cases even allow, part-time work for their students. A low-intensity school will have a similar class load but will require less homework and self-study in order to keep up with the class curriculum and pass the course.
