It’s a well respected institution and it’s graduates are well regarded by employers.
Only a small minority of degrees have modules that can be studied this way. You need to show some evidence that you’re capable of study at this level. For my Finance Master’s[2] a MicroMaster’s in International Law from UCLouvainX[3] sufficed. It’s also difficult to get the Master’s in the minimum two years this way because they won’t let you transfer from studying individual modules to doing the Master’s without your exam grades having been released and being satisfactory, though it is possible to do it in two years if you start with the first session of the year.
