8th and 9th graders that verbal are the ones who transfer the most because their parents help push the initial choice. Then when they get to college sometimes 5 years later, their ability level might not be what it once was and they find themselves on the bench for the first time in their lives and they don't like it so they transfer and start a new.

11th graders that commit have the most success (even if they don't get then most money). Almost fully mature. KNow what they want to go to school for and its easier to judge their ability to kids currently on the college team
