It depends on the degree you want, the requirements of the program (those are not standard), you, your motivation, your project, your adviser, and your committee.o get a PhD, you can either do a masters first, or enroll in a PhD program after the bachelors, in which case you'd take the masters coursework before working on the PhD even if you don't get a masters degree specifically (this is called masters en route).
Generally it takes full time graduate students 2-3 years to earn a master's degree and 4-5 years to earn a PhD. This is assuming they go for the same subject that they hold an â¦ undergrad degree in.
