Research, GPA, recommendation, GRE, etc.. There are many things to go to grad. Which one is the most important? One of my friend had very good GPA, but he did not get admission from any schools. His GPA was 3.95. Actually, his major was BIO, and he got all As from major, and only one B from general course. Of course, he got good GRE score, but He had never been research or publication. I don't think he got bad recommendation... I know some math or any science student go to engineering school, but I can't know what the student is different.. who can go.. who can't go..
