I have got an email of invitation to review a paper in a best journal of my field. I had a paper there and somewhere else almost in that field.
As I must invest serious time and attention to complete the review, I wanted to know if that does any advantage on improving my resumé for getting a better chance of acceptance and scholarship for my future PhD program abroad? Basically, should I mention in my CV that I am a reviewer of that journal, when I am sending it to other universities?
P.S. I have graduated from M.Sc. two years ago.
