I would argue that the degree you do is not representative of your level of intelligence, or whether you are a "high acheiver" as such. A person with a UAI of 97 may choose to do an bachelor of science/ arts/ whatever degree requiring a score of approx 60, work incredibly hard and be motivated to do their best towards their chosen career. Obviously some degrees are more difficult or require more effort than others, however this is not indicative of a person's intelligence, interests, personality, motivation, attraction.
