Online bachelor CS degree to prepare for a master CS program

[dfrecore]

Thanks so much for the inputs, everyone! From your answers I have gained a lot of insights and really appreciate them.

Totally agree that getting letter-graded credits from TESU is expensive, but for now it seems that TESU is my only choice to earn a CS bachelor degree in the shortest time possible.

I realized that doing 39 credits in two terms won't be feasible. So I have reviewed the list of TESU CS courses and pick 10 courses (see below) that I think should be letter-graded for the sake of OMSCS admissions (I also emailed my list to OMSCS and will have an update here once I hear back from them).

So now my plan is paying flat-rate for two terms and completing all 10 courses (30 credits) during that period, and then pay per-credit for the capstone. So my final cost would be: 
$4,928 * 2 + $1,527 = $11,383 
(not taking into account cost for completing the remaining 87 credits with external providers like Study.com and OnlineDegree.com)

I know doing 5 courses per term while working full-time is still hard but I'll try my best. Also I'm already familiar with many topics in these courses thanks to my work experience so hopefully that may help. What do you think about this new plan?

Code:

[Pay flat-rate for two terms]
Introduction to Programming
Programming Languages
Data Structures
Calculus I
Discrete Math
Operating Systems
Computer Architecture
Computer Arithmetic Algorithms
Software Engineering
Artificial Intelligence

[Pay per credit]
Capstone

 
Also thanks for your suggestion on University of London's online BSc in CS. It looks like a good program and I'll definitely apply to see how many credits I'll be exempted.

I might be a little more selective in which courses you get graded credits in.  Intro to Programming, a programming language or 2, calc I - no.  I think you spend your money on the UL courses to get the biggest bang for your buck.  Even if it's fewer credits, or you choose a few interesting courses that are IT-related that might not fit in your AOS, I think it's worth doing instead.

If you still want those courses graded, I'd find a much less expensive way to get that. An inexpensive CC or other option is a better way to do this. NMJC is fairly cheap for online courses for out-of-state students, Westcott courses has Calc I for $569 and it's self-paced, I'm sure there are more ways to get these LL credits graded for a lot less than TESU.
