Will GMAT be relevant for any course in Ireland or should I do it or not for a MBA/Master's?

It depends on the program. GMAT is mainly required for MBA courses in Ireland - for example, top schools like UCD Smurfit and Trinity College Dublin expect a GMAT score (typically around 600).

For most other master’s programs, including finance and business analytics, the GMAT is usually not required. These programs focus more on your academic background and English proficiency.

With your BCom degree and GPA, you likely don’t need the GMAT unless you’re targeting an MBA.
