Hello,

In order to apply for MS in Physics, you may have to appear for GRE if you are applying in the Universities of USA or Canada.

You may want to shortlist the locations of your Universities before preparing for entrance exams, as many countries may not need you to appear for GRE. The procedure for admissions in Universities abroad vary based on their locations.

Many East Asian University may offer you scholarship (eg:MET) however you may not have to appear for any entrances, these universities will focus on your work portfolio, your SOP and strong LORs and Language Exams.

Whereas universities in USA or Canada may expect you to appear for GRE.

I hope this helps.
