You can find this achievement in the MyCareer section of the game.
It is important to note, that in order to get this you CANNOT skip ahead in the "story" to get this. You skip ahead by going to MY NEIGHBORHOOD in the career options page. Doing this declared you for the NBA draft immediately and you skip the college part of the game, thus negating this achievement.
In order to get this achievement you will need to play 3 or 4 High School games. At one point during the career, you become hurt and you can choose to play the game slightly injured or sit it out to play healthy in the finals. It doesn't matter which you choose. It also isn't really too important how well you do. I averaged about 8 points, 6 assists and 4 rebounds as a point guard in high school and still got to pick ANY college I wanted, then skipped the college career totally, having a pick of multiple NBA teams to join.
So, in short:
Start a player in MyCareer.
Play about 4 high school games without skipping.
As soon as you choose a college, the achievement will pop.
You can then keep playing college games to earn points and skills, or jump straight to the NBA
