An independent study is student-specific. There is no curriculum of courses, but rather one course with its syllabus tailored to the level of knowledge and abilities of the particular student. Each student is best qualified to determine what is most interesting and sufficiently challenging for him or her and what would be a reasonable workload within the given time constraints.
Students vary widely in the quantity and quality of their work in a semester course.
Without interviewing a student and reviewing his or her prior formal education course work, it is difficult to be more specific. A useful independent study design allows the student to pursue whatever may come up. All or part of one book might be enough for the reading module, and the selection could be anything of interest that is relevant to the study.
