I already have a postgraduate degree
Our verdictAlmost certainly not. You need one field, not a second degree.
A second master’s rarely changes anything a first one did not. If there is a specific capability you are missing, buy that capability — it is available in one year for a third of the money.
What to check
- A PG diploma adds one field to the qualification you already hold.
- The exception is a rule that names "MBA" specifically, which some corporate policies do.
- If nobody is asking you for it, that is your answer.
