Overall my experience with i-to-i was not brilliant, the courses are very inflexible, with "admin fees" at every corner. The course content is very basic and taught me very little i didn't already know, however it did go through the basics with some competence. I found the layout of the material to be incredibly poor at some points, and found several typos and structural issues. I've included some of the notable examples below: In the "pronunciation" section the content immediately assumed the learner to have a southern RP English accent. As a Scot I found most of this section incredibly unhelpful and I'm sure the majority of brits who don't have a southern RP English accent would agree, and would have appreciated at least a disclaimer at the start of the section (there was a very small disclaimer at the END of the section. Not helpful). The wording of many of the quiz questions was confusing and needs reviewing. At unit 7.5 the course covers tenses. The introduction shows the tenses in chronological order, but the later content follows in a completely nonsensical order. These are just some small examples of problems I found with the course in general, so that I overall found the content pretty unprofessional and unsatisfying, especially for the price I paid. Add on to this the administrative fees and certificate fees and it's just mad. With that price I expect much more detailed tutor feedback (which was very basic) and course content that flows in a logical way. I have two reasons for giving two stars instead of one: the first being that the course really does cover the basics well, it's just vastly overpriced. The second being Amy from customer service, who listened patiently to my tirade about my poor experience, quickly and efficiently sorted out my certificate issues and was overall incredibly helpful. I would give an extra star just for her but I want to be honest with my review. She deserves a raise.
