I studied full time, but lots of people study part time. I think with part time you can choose do to 1 or 2 modules per semester. A lecture lasts 2 hours with a compulsory 1 hour seminar. When I was full time, I had 3 classes per week, so you will have 1 or 2 classes per week! Course is difficult, but manageable! Lots of independent study time and reading to do!
