If you are asking for our personal opinions, here is mine. Graduation rate at specific school has nothing to do with the success of a specific student at this school. NONE. The success of a specific student will solely depend on the efforts of this student and absolutley NOTHING ELSE. If a person has a goal of an A in every single class (and many in certain academic tracks have to have such a goal to be successfull at the end, so I do not see why not everybody has such a goal), if such a person has a plan how to accomplish this goal, why this student would not graduate and what his specific goal / plan has to do with the graduation rate at this college?
It never occurred to us to check the graduation rate at any college, when D. applied to them. She simply said: “I will do fine anywhere” and opted to attend in-state public that matched her personality and very wide range of goals and interests including potential ones. The graduation rate was not even any criteria in her selection and neither was college ranking. We forgot to check either. The result - D. graduated with college GPA = 3.98 and had a great selection of Medical Schools that accepted her.
