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.
Answer   I think you start your first period when you are about 9-13 years old.I started my first period when I was 10 years old and I was in 4th grade during that time sâ¦o I don't think I started my period too early. 6 people found this useful. CatRox.
The first period happens for many girls between the ages of 12 to 14 years, but quite often it is earlier (from as early as 9 years old) or later (up to 16 years). Girls start having periods at different times depending on how quickly they are developing. If a girl has not had her first period by the time she is 16, this is still probably normal, but it would be worth checking with a doctor. Once you get your period, it may take quite a long time for your body to settle into a regular pattern â maybe up to a year â but most women eventually do get into a regular cycle.
