Did Professor Teach Wrong Course for Semester?

A faculty member at Lone Star College taught the wrong chemistry course for a semester, KHOU News reported. The television station told the story of an A student surprised to find she was failing introductory chemistry. But the professor eventually said that she had been teaching a more advanced course. The student said that the professor made up for the situation by raising everyone's grade. The college and professor aren't commenting, but KHOU confirmed the story with another student in the class and through an email in which a department chair said that teaching the more advanced course was not intentional.
