Most business programs consider some kind of writing credit as part of their general education requirements. Expect to take one or two basic composition courses. In these classes, you hone your abilities to form a well-defended and grammatically-correct thesis.
Prepare yourself to gain comfort speaking in front of people because most business curriculum requires a type of speech class. Depending on your specific school, you may also be required to take an interpersonal communication course. You might find that you can substitute an interpersonal class for a public speaking course but typically this is not the case.
As part of your general requirements, you will likely also need to take a few courses that are science-based. You could be required to take a course that has an accompanying lab or one that just requires class time only. Expect to choose from subjects like chemistry, biology, astronomy and geology.
To further fulfill general education requirements for a business degree, likely you will take several courses in arts and humanities. Classes in these subject matters are also referred to as liberal arts courses. There is usually a broad range of subject matter that fulfills your credits in arts and humanities including psychology, sociology, literature, fine arts and history.
Because the degree you're pursuing is a Bachelor of Science, expect to take more math courses than would be required for a typical Bachelor of Arts degree. Depending on your skill level, you may begin with an algebra or pre-algebra course. If you're entering the program from high school, your starting point may be further along. It's not unusual to need to successfully complete a college-level calculus course in order to gain admittance to a business management program.
Since your interest is in business, few of your prerequisites will likely include intro-level business courses. Titles for these credits are usually general in nature, such as "Introduction to Management." These classes are important for you to gauge whether or not the subject matter is what you expected and if you'd like to keep business management as your degree choice.
