A bachelor's degree typically requires the completion of around 120 credit hours. This generally translates to about 40 courses, assuming most classes are worth 3 credits each

. However, the exact number of credit hours can vary depending on the institution and the specific degree program. Some programs, such as engineering or education, may require more than 120 credits, sometimes exceeding 140 total credit hours

. Additionally, students pursuing double majors or specific concentrations might also need to complete extra credits

. Credit hours are usually distributed among general education (core) courses, major-specific courses, and electives. Core curriculum requirements can vary by university but often make up about half of the total credits needed for graduation

. In summary, while 120 credit hours is the standard benchmark for earning a bachelor's degree in the U.S., the precise requirement depends on the program and school policies.
