Once you enroll, you'll gain full access to all program content, including core and career projects. We recommend working on career projects after making progress on core projects.
Career projects are optional and do not affect your graduation. However, if you plan to submit your career projects for review, this must be done before completing the graduation steps in the classroom. You won't be able to submit projects after graduating.
You can also take advantage of Udacity's Career Resource Center to get advice, guides, and resources on topics ranging from job boards, interview practice, and career exploration.
