Terrible. The course content was extremely poor, most of it obvious, the quizzes and tests were even worse, again, most questions could be guessed easily and were frankly stupid, something along the lines of ‘if a student gets a question wrong should you A. Shout at them so they don’t make any more mistakes or B. Explain the answer. But worse than the course is how extortionate i-to-i are. I have been forced by them to pay various ‘extra’ fees throughout the course. The worst of which was for assignment extensions. I found that when marking assignments they had a tendency to only give you part of the corrections needed, then when you have corrected it and sent it back they would take 7 days to mark it, then give you the next thing that needs to be corrected and so on until you ran out of time and have to pay an extra £40 or so for a 15 day extension. Why not just give all the feedback at once? Other things they charged me for was an email from them confirming that i was doing the course, why you would charge £20 for an email stating I was doing it I cannot imagine... But they did all the same, disgraceful behaviour. I strongly advise anyone to avoid i-to-i.
