Types of universities
Four-year institutions offer a full bachelor's degree programme, whereas two-year colleges (often called community or junior colleges) usually offer an associate degree programme.
You can choose between public and private institutions. Public institutions such as state universities often have larger campuses and student numbers than private institutions. It is important to think about the type of campus setting that interests you as well. Large versus small, city versus suburbs, and so on. It must feel right for you.
