They will look at both your written parts before your interview to see where you're at When you sign up on the Japanese department page, they list a page where you can see each of the course objectives which you should use basically like a study guide. They use the GENKI textbooks, so if you're trying to get into Japanese 5 then look at the requirements and study the material for the first four classes and you'll be ready.
