they want kids to play sport in

college all 4 years. If you are good at both, but not going to professional, they know in some point you will quit to play for school and concentrate on your study. My son applied for top science major in those schools and they know nobody could do both good at same time. It's safe to chose the kids already proofed themself that they are 100% dedicate to science. Of course, if you chose major in economy, spanish, english or communication, you poosible fine. all I said is for top schools, not the regular schools.
