How good are the Study.com TECEP prep courses?

[Merlin]

I took the Public Relations TECEP, I thought it was hard (and I've taken a bunch of tests and courses).  The textbook was very dry and boring, and I kind of gave up reading it through after a while and just decided I could probably pass based on what I'd read and the IC cards.  I did pass, my grade wasn't great though.

Hmm, I've read that Public Relations was one of the "easier" ones, even for folks without domain knowledge in that area. I don't need the Applied Liberal Arts math course which is suggested as the "easiest" TECEP, so I'm curious what you'd recommend instead of Public Relations?

It looks like many of the exams require essay questions now, which I prefer to avoid in a timed exam setting, so the non-essay based TECEP exams I am considering (at least those relating to my BSBA GM AOS) are:

• ACC-421-TE Federal Income Taxation (UL, GM AOS, accounting area)
  
• BUS-101-TE Intro to Business (LL, free elective? not sure if this will fit in GM AOS)
  
• COM-210-TE Public Relations: Thought & Practice (LL, GM AOS, marketing area)
  
• FIN-321-TE Security Analysis and Portfolio Management (UL, GM AOS, finance area)
  
• FIN-331-TE Financial Institutions and Markets (UL, GM AOS, finance area)
  
• MAR-323-TE Advertising (UL, GM AOS, marketing area)
  

I tend to fall asleep if I try to read stuff that is too try and/or boring to keep my interest. Which is why I'm looking for alternatives to textbooks like Study.com since I seem to do well with their teaching style (96%-98% on all the courses I've taken so far).

But, these are not Study.com exams, so I have no idea how close the material they provide matches against the TECEP exams. Given they're a TESU partner, it would be nice to believe they would have some kind of arrangement to make sure the material matches, but I don't see a confirmation of that on the site.

It would be helpful to find someone who has used the Study.com material to prep for a TECEP to get an idea of how close their prep materials matches against the exams. I have to assume there are at least a few people here who have used Study.com resources for this purpose.
