I've signed up for the free 4 week trial. I'm not overly impressed with service/delivery at the moment.
The course content itself is great.
I'm really getting annoyed with the pushing of buying extra content - pop-up screens every time I log in or change page. I know I'm on a free trial, but with how pushy they are it's actually turning me off wanting to move to a paid subscription.
Also it has been really frustrating trying to change scheduled class days/times. One of their seeming marketing points is "your study, your way" or something like that. But there's actually more restrictions on how much you can do per week, and rescheduling of you miss a class, than any other study I've ever done (and I have a uni degree as well as numerous diplomas).
The user platform is simple if you are able to stick to the schedule you initially set up. But if you need to change your schedule for any reason, it becomes complicated and painful real quick.
