People don't jump class in life. From how good looking they are, to how smart they are, to how strong they are, to how well they play sport xyz. Carry on
A dr has a height chart for kids and knows how tall they will become as adults.
In first grade, we know who the smart kids are and who the dumb kids are, and it doesn't change in middle school, high school, or college.
In first grade we know which kids will be fat and which will be skinny.
In first grade we knew which kids will be mean and which will be nice.
In first grade we know which kids play the best sports at recess, and which can't catch the ball.
All these traits/abilities/genetics/desire/whatever you want to call them, stick around for life. Maybe a very small percentage of exceptions.
