pkahler's sibling post also brings up an important side point: beyond the basic core, what you study really needs to be focused on what aspect of the software industry you want to be in or are likely to find yourself in. While I, too, encourage you to take C/asm courses or whatever your preferred focus is, the bulk of the jobs in the industry are in creating web sites and business systems (much of which are so-called CRUD apps; see https://en.wikipedia.org/wiki/Create,_read,_update_and_delet...). Even if you plan to do something else, a course in databases and concurrent programming will stand you in good stead as a fallback if your career doesn't quite go as planned.
