Here are a few examples from me (PG math and language), DC18 (E2 and in any category on any given day), DC15 (MG/HG), and my dad (EG/PG in math only) all at around 12:
DC15--curious about science and how to conduct her own chemistry experiments, avid reader (early high school books), enjoyed school and learned at school, when bored would memorize and perform SNL sketches for us
DC18--very concerned about social justice in community/world/school (even to the point of getting suspended for taking a stand against racism), memorized everything from history documentaries and sports broadcasts, frustrated with not being able to read what he preferred to read, grade level/some advanced for most subjects but understood the concepts (especially humanities) for late high school/college material, looked for meaning and purpose in life (translation: lots of late-night philosophy discussions)--aside, also from college applications, scores on ACT/SAT varied wildly from one test to another
Me-- preferred Russian novels for silent reading class, taught myself calculus and college/medical school science out of old books before school and during the summer (start of 4 am wake-up time after losing a discussion about how late I could stay up reading at night), staged a mini coup d'etat and boycott in catechism class after injustices committed by the church and again in response to being forced into the 12-y-o student mold at school (i.e. making a Fibonacci sequence on standardized tests instead of taking them)
Dad--forced by parents into learning German resulting in a boycott of class and a 0 on his report card, figuring out many principles of statistical analyses to apply to baseball games in lieu of access to higher math courses
It seems as if a lot of factors influence achievement and manifestations of giftedness, especially in PG kids (flunking a class or standardized test as a protest, for example). It seems as if the only rule for PG kids is that they are as different from each other as they are from age-mates...
