The TOEFL needs to be taken within 2 years of the time you would be starting your program at UC Berkeley. For Fall 2022 admissions, TOEFL test scores are valid as far back as June 2020. The GRE needs to be taken within the last 5 years of starting the program. For Fall 2022 admissions, GRE test scores are valid as far back as 2016. What is the institution code for the GRE and TOEFL exams? The institution code is 4833. Departmental code is no longer required. My GRE scores will not arrive until one week (or two weeks) after the deadline. Is this a huge problem? As long as your application is submitted by the deadline we will accept GRE scores that are two weeks late. However, if other things are late as well, there is a chance you will not be considered for admission. Are international applicants required to take the GRE? Yes, all applicants, domestic and international, are required to take the GRE exam. What are minimum GRE scores? We do not have a minimum GRE scores required to apply.
