What\'s the price of leaving high school unprepared? Ask Chelsea Stephanoff, a Wayne State University student who is spending nearly $600 this semester for a class that won\'t count toward graduation. Why? Her math skills were poor enough that even after four years of high school math, she was placed in a remedial class. \"Math is not my strong point at all. I\'m horrible at it. I have a hard time focusing on it,\" said Stephanoff, a fourth-year student from Shelby Township who wants to be an elementary school teacher. She is not alone. Teens leaving high school with substandard skills tax the colleges that must bring them up to speed -- and cost themselves big money for classes that don\'t count toward their degree. It\'s one of the reasons Michigan -- along with other states -- is looking at a state-mandated curriculum. The problem is clear in the enrollment for remedial math at Wayne State , which has soared 85% in the last four years. There are 1,200 students in 12 sections of the class, a computer-based course. \"These students are coming in at the level of ninth-grade math,\" said Patty Bonesteel, developmental math coordinator at Wayne State . \"Without a doubt, the idea of being bad at math is perfectly fine in our culture, and that\'s unfortunate.\"
