For persons who combine a master's degree and a PhD at the same institution, 5 years seems to be a typical length of time to completion. With the AuD degree being so new, it is currently unclear how long a PhD will take after the AuD or the length of time to complete a combined AuD/PhD (research degree).et's assume that a PhD is finished in about 4 years. The first 2 years will include taking courses, many of which will be courses from outside the CSD department. The choice of course work varies by student but always includes several research methods and statistical analysis courses.

Your first menstrual period is called menarche (say MEN-ar-kee). It usually starts sometime between ages 11 and 14. But it can happen as early as age 9 or as late as 15. If you are a teenage girl, see your doctor if you have not started having periods by age 15. Menarche is a sign you are growing up and becoming a woman. Along with starting your period, your body is changing. You've begun to develop breasts, pubic hair, and underarm hair. And your hips have begun to widen. Menarche also means that if you have sex, you can get pregnant. You can even get pregnant in the month before your first period starts.
