Most classes offered by the university are posted on the Albert Course Search. You can access the Public Course Search through the Albert landing page, or via your Student Center shopping cart. (The advantage of the first option is that it’s quick—no login required; the advantage of the second is that it allows you to add classes to the shopping cart, which, in turn, allows you to validate them and eventually enroll in them.)
Make sure to use filters on the right-hand side of the course search to make finding classes more efficient and more productive. First, select the term: in this case, Fall 2018. (Though it seems like the only option, you’ll want to check the box, to ensure that Albert returns only those classes being offered in the coming fall semester, rather than potentially pull up archived courses that may not be applicable.) It can be helpful too to set the Academic Career filter to “Undergraduate”; the “Open/Closed/Waitlist” filter to “Open,” to see a list of available courses; and the “Units” filter if you are interested in, for example, 2-unit options. Once you have set your search parameters, you can select specific departments. Within each department, you will see a list of courses (typically, though not always, accompanied by a description, which, if one is available, you should of course read carefully). Make sure you also open the notes section for courses of interest: when you click on the green sideways arrow—“Click here to learn more”—you’ll see the course meeting days and times, as well as other important information, including pre-requisites and other restrictions on registration.
Ideally, you will set aside an hour or two to look through the course offerings in all departments where it is possible for Gallatin students to take courses. (Consult the ARG for an overview of “NYU Undergraduate Schools and Their Course Subject Areas.”) Departments often offer courses you might not immediately and obviously expect: for example, language departments in CAS will often offer literature and film courses, taught in English; the CAMS—or Child and Adolescent Mental Health Studies—program is a source of psychology courses; the undergraduate offerings of the Wagner Graduate School of Public Service look at public policy and social entrepreneurship.
A final note: not all departments will annotate their course offerings, and we encourage you to take a look at the course descriptions posted on departmental sites, especially when the department in question is of particular interest. In some cases, this is the only way to see a course description: for example, the comparative literature department in CAS offers descriptions of its classes only on its site. It can also be helpful to get a sense of a department’s structure and expectations, and the best way of doing so is through the site.
