I currently teach at N.D.I and can say that I regret joining the company. N.D.I charges extortionate fees for Very poor material. Once they have the students money, they couldn't care less about their education.Lessons plans with spelling errors, bad English, missing words. Lessons set for beginners repeated and given to upper intermediates as new lessons. Material directly cut and pasted from websites.One lesson is meant to be about travel in New York and the idiot who designed the lesson clearly just copied an advertisement for a website, paying no attention to the material. The list goes on.I feel badly for the students that get sucked in by their slick image and promises.I will not be resigning a contract. N.D.I is a slickly presented sham.
