Christina is most likely in Formal Operational Stage of Piaget's stages of cognitive development. Because in this stage, adolescences already have logical skills on using symbols applied to abstract concepts like science and algebra. They have now the ability to think of multiple variables in organized ways, consider possibilities, and formulate hypotheses. They also have the ability to examine concepts like justice and abstract relationships.
