Hello!
Studying at a Postgraduate level can be a lot of hard work, especially if you're working a 9-5 job, but it is manageable.
If you are studying on a master's course, luckily the hours are less than undergraduate level as the university expects you to be working alongside your subject area.
I was worried about the workload too, so I'm currently doing my MA part-time. So I'm only in one day a week and doing one module at a time. It's worked out so much better for me with my study time and tuition payment instalments.
Even part-time if you find the work too much, the staff are there to help and accommodate you when you need some extra help and support.
What I'm trying to say is that it is a lot of work and sometimes that can be difficult to manage, but the university will be there to support you as they understand you might have jobs and families and other commitments to consider during your studies.
As long as you are able to put aside a few hours a week for study and assignment preparation, you should be fine.
I hope this helps,
