The point to remember, if you are applying from Level 7 to Level 7 course in the UK, the UKVI wants to see the progression.
As an example, let’s consider you’ve already completed an MSc in Business analytics and now want to study MSc Human Resource Management course.
Some universities are flexible, and some aren’t flexible. For example, BPP universities would accept MSc Management/Project Management or MBA courses even though someone has a master’s in business analytics. However, some Universities (like Hertfordshire) do not want to accept students for second masters. It’s all about their policies and student’s case.
