When you get lost, you can reorient yourself with a compass. Reorient can also be used figuratively. You got off track with your college plans, but now you have reoriented yourself, and you are applying for the fall semester.
The verb reorient has orient as its base. Orient is from the Latin word orientem, which refers to the sun rising in the East. In fact the verb orient meant to face East, so reorient literally means to face East again. Today, reorient is to adjust to new circumstances or positions. The curriculum will reorient student learning goals, but it also means you have to learn the new, new, new math.
