The International textbooks are very flawed though. Special Programs and English Programs are better in terms of professional English.
EP, Special Program: How to write a resume and cover letter, how to write a 5 paragraph essay in many forms and on many topics, how to use APA formatting, how to write letters and emails, how to speak in a range of situations, acting and drama. How to read a graph. How to make and give presentations. Improptu speaking. Also many other subjects taught fully in English.
The books are clean and modern. Very easy to use with full online support.
International: women are good here is a list of 3 athletes and a nurse. Africans are poor, lets read this 8 page article. I swear one page got the continents of the world wrong. We did a 2 hour lesson on how sitting down increases your chance of dying. We sat for the full 2 hours no break. International English is more about politics than English skills.
And the books are so messy. Its like page 5, 6, 7, 8 reading, questions on page 2 and 9. So frustrating.
