I really enjoyed the Cambridge Legal-English distance learning online course which lasted about six months. I had the chance to write, read, and speak English intensively!
The online distance learning private tutorials lasted about one hour every week and were performed via Skype. I had two tutors listening and giving me feedback.
The whole setup of the course is really simple. The only thing you need is the coursebook, a computer, and free time.
The two tutors I had were great; they were very flexible, and they always gave me helpful feedback.
During and after the course, I felt stronger in speaking and writing English.
When the course was finished, I missed my weekly private tutorials, as they had become a favourite habit.
Summarizing, I firmly recommend this interesting distance learning experience because it is effective and you can learn wherever you are.
There is no need to visit a classroom; I did nearly the entire course on Sunday mornings in my pyjamas at home.
