A Google search for Oxford Seminars Reviews shows, when excluding the company's cherry-picked reviews and advertising, that Oxford Seminars, an accreditation program to teach English as a second language (ESL, TESL, TESOL) is probably worth the money. Most people on various review sites seem to praise the book as being instructive and practical. Based on those reviews, and a suggestion from a friend that I take the course, I decided to read the entire book (cover to cover), take the course, and report my findings as I went along.
