Is the GRE exam valid for five years and will it be helpful for my application in Ireland/New Zealand for a Master's?

Yes, GRE scores are valid for five years from your test date.

For master's applications in New Zealand, Ireland, and the UAE:
- New Zealand: Most universities do not require GRE scores, but some competitive programs may consider them.
- Ireland: GRE is generally not required; admissions focus on academics and supporting documents.
- UAE: GRE requirements vary by institution and program.

With your strong academic and professional background, a GRE score could strengthen your application if the program considers it. If not required, focus on your academic record and supporting documents.
