When you go to university, you start by doing your 3- or 4-year undergraduate degree. In most places, your undergraduate degree is a bachelor's degree. After you graduate from your undergraduate program and receive your bachelor's degree, you can then choose to complete a graduate (sometimes called postgraduate) degree. These degrees include master's degrees and doctorates.
