For most careers, there are member groups consisting of people who work in the field. These groups often allow students to join for a reduced rate. To find an organization of those working in the career you plan to pursue, search for the career that interests you, and add the site: command to limit to the .org domain.
Example: Interested in a career as an attorney? Type the following in the Google search box:
attorneys association site:.org
Do not include spaces between site: and the domain (.org).
If the career you are interested in is more than one word, like medical assistant, enclose the phrase in quotation marks. Here's an example:
"medical assistants" association site:.org
