Most business schools accept applicants from a wide range of undergraduate backgrounds, which can mean that some applicants who are otherwise strong may be weak in some of the subject areas that will be important in business school—for instance, quantitative methods (such as calculus), computing technology, and statistics.

During the application process, find out whether the schools to which you are applying will want you to have taken specific courses before you enroll, to address any academic deficiencies. Some schools may offer you admission on the condition that you complete certain courses prior to enrollment. Chances are, most schools on your list will have similar prerequisites.

Take an honest inventory of your weaknesses and take steps to complete prerequisite course work early in the admissions process and before your planned enrollment date. If your quantitative skills are weak, take courses in calculus or other topics to strengthen your skills and improve your application. Even if you do not need to, you might want to take supplementary courses before you are offered admission, just to polish your skills.
