College professor accidentally teaches wrong course for entire semester

Students at Lonestar College near Houston say their professor taught them the wrong course for months before realizing her mistake.

The students signed up for an introduction to chemistry course, but what they were taught was much more advanced, they told KHOU. It wasn’t until shortly before their final exam that the teacher admitted her mistake and added extra credit to their grades.

The school says the correct course was taught, but the head of the chemistry department admitted in an email that a mistake had been made.
