Hi DK,
I am about 8 months into the Uni of Hertfordshire online MSc Computer Science (with Software Engineering) and I'm really enjoying it.
I've answered a similar question in another post, so I'll copy and paste my response below:-
'I spent a long time looking at online MSc Computer Science courses, and after much deliberation I went for the University of Hertfordshire online MSc Computer Science. You can do straightforward Computer Science or you can combine it with a specialism, such as Software Engineering (which I chose), AI, Cyber Security, Data Science etc.
I found that a lot of the other universities don't teach the courses themselves, they simply give their name as an affiliate, but then the actual course has little to do with the Uni and is outsourced to a third party company, with their own instructors & materials. I read lots of mixed experiences of this model, more bad than good, when I was looking into the options.
At the University of Hertfordshire, the courses/materials are put together by an actual lecturer from the university (matching specialists to the particular module in question), and you have 4 hours of live sessions per 8 week module with that tutor (as a group), and they are always available to answer any questions at any time - I have certainly found this to be the case. They also set and mark the coursework/tests themselves, so there is a lot of assistance and feedback should you want it. You feel like you are actually part of the university to some extent (as much as you can with online learning!).
I am really enjoying my course, it does take time & effort, and it is mostly self study of the materials provided, so it's very different to an on-campus experience (I did my bachelor's in the traditional way). You have to be fairly disciplined and self motivating, but I have learnt so much and am finding it a great & rewarding experience.'
I hope that this helps? I'm really glad that I signed up for it and I think that I definitely made the right choice.
Please let me know if you have any other questions I can help with

Eve
