The PhD is the highest degree you can earn, so it follows that it demands the most work. In most cases, you complete a masterâs degree before going on to a PhD. Unlike a masterâs degree, a PhD usually requires a series of comprehensive written or oral exams.
A PhD is the highest degree you can get. However, it's not a medical degree. It's a research degree. A medical degree is an MD, which takes 4 years of med school after the bachelors, and includes internships/residency after that (3-5 years). Depending on what you want to do with the PhD, you might need a postdoc (2-6 years of working in the field in temporary positions).
