Military students in grades kindergarten through 12 will find rewards for their academic success waiting for them at exchange stores. The Army and Air Force Exchange Service (AAFES) is continuing its You Made the Grade program for the 12th year. Young scholars who hold B averages can get goodies like a free Burger King hamburger kids meal, or Subway six-inch combo, magazine of their choice, or free hamburger – and more. They also can register to win shopping gift carts of $2,000, $1,500, or $500. Student scholars need only to present their military identification cards and proof of their B average.
