The median estimated time in coursework and exams cannot be directly compared to the total median time in program used in indicators II-29a and 29b because the questions about time in particular stages of doctoral study are worded differently. The question on coursework and exams reads “How many years were you taking courses or preparing for exams for this doctoral degree (including master’s degree if that was a part of your doctoral program)?” and asks respondents to round to whole years.
