What are the easiest majors to study with alternative credit?

[Pelican]

Many majors are difficult to study at the Big 3, at least using cost-cutting solutions, as it is difficult to find sources of cheap upper level credit.

I'm aware that these majors are fairly easy to achieve using alternative sources of ACE credit, such as Study.com, Straighterline, etc.:

• Liberal Studies
  
• Business
  
• History
  
• English
  

Did I overlook any? Are there any other majors where one can easily find upper-level credit to using one of the highly affordable alternative sources of credit?
