Day before interview. What should you do?
Remember, the program you are interviewing with liked what they had seen in your application. Otherwise you wouldn't be there. Now it is time to prove that you are who they have seen in your Personal Statement and CV. Your scores do not matter anymore. Now it is only about yourself: Your personality, Communication skills, and how good of a team player you make. You cannot guess what exactly the program is looking for. Your best bet is to be YOURSELF!
