Jesse1: The highest SeeD rank possible to get from the test is 10 (it's what I got after getting 100 in everything, including bonus). Something weird happened, though: I raised my level to 12 (by passing 2 written tests) and later (after the dance) in the morning of when Selphie wakes you up, my SeeD rank just went up by 15 (up to rank 27) on my way to the main gate (I just got the first pay then).

Peter_18: Have you tried chalanging the people around the dock area of blamb?
