[TESU] BA in Computer Science, need help with planning

[Nixi]

I'm currently completing business-related courses and am on track to graduate in September with a BSBA in Computer Information Systems, however I'm now also considering the idea of switching to a BA in Computer Science instead.

I'm not sure I'll be actually doing this, it just depends on time, cost, and other factors.

• A: Introduction - I can fulfill these credits with StraighterLine's Intro to Programming in C++ course.
  
• B: Data Structures - Not sure
  
• C: Discrete/Linear - Not sure
  
• D: Calculus- I can take both General Calculus I, and General Calculus II from StraigherLine to fulfill these credits.
  
• E: Electives-
  
  1. Group 1, 12 credits needed - Not sure
     
  2. Group 2, 6 credits needed - Not sure
     
  
  

If anyone has any recommendations to fulfill all the courses I'm not sure about (preferably away from TESU and not too expensive), any suggestions are appreciated!
