to transfer up to a maximum of 64 credits from other accredited post-secondary institutions, but 64 credits must be completed at Harvard. Students select one of three "areas of concentration" which are humanities, science, and social sciences. ALB degree candidates are also required to complete a minimum of 16 on-campus-only credits at Harvard; students must also complete a minimum of 12 writing-intensive credits and earn a minimum of 52 credits in courses that are taught by Harvard instructors. In addition to a concentration, degree candidates have the option to pursue one of twenty "fields of study" (similar to majors). In order to successfully complete a field of study, students must earn a B− or higher in 32 Harvard credits in one field, and maintain a B average in the field. Students may also complement their degree with up to two minors. Undergraduate admissions Undergraduate degree programs require pre-admission courses as well as a formal application process. Students must also hold a "high school diploma or its equivalent [which] must have been earned at least five years prior to enrolling in any ALB degree-applicable courses." Students applying for degree candidacy must complete three 4-credit liberal arts courses at Harvard with at least a B grade in each, and maintain a minimum 3.0 cumulative GPA. One of these three pre-admission courses must be EXPO E-25. To enroll in this course, students must either pass a placement test, which measures critical reading and writing skills, or enroll in EXPO E-15 (a course that acts as a precursor to EXPO E-25). Students failing to earn at least a B in a class can retake it once. Those who meet all these criteria are then eligible to apply for admission into the school's undergraduate degree programs. Master of Liberal Arts (ALM) The Master of Liberal Arts in Extension Studies (ALM) includes 19 liberal arts fields of study and seven professional degree programs (Biotechnology, Information Technology, Journalism, Management, Mathematics for Teaching, Museum Studies, & Sustainability). Except for Museum Studies (10 courses), all ALM candidates must complete 12 courses—48 credit hours—with most requiring a thesis or capstone project crafted under the direction of an instructor or faculty member holding a teaching appointment in the Harvard Faculty of Arts and Sciences. Graduate admissions Application to a graduate degree program requires an accredited bachelor's degree (or foreign equivalent), passing the Test of Critical Reading and Writing Skills, the completion
