Do you have to be super smart to finish WGU? What can you do to eliminate any doubts

[whiverem]

I think WGU takes most people. If you weren't initially accepted I think you can take some classes with WGU and should be accepted.

I was accepted without any problems. I've passed CLEP and DSST exams. I feel a little insecure about my reading ability. But I do read websites all the time and learn all kinds of IT/computer related stuff.

Should I re-read the material multiple times?

Do the general IT, computer science, software engineering majors use something like zyBooks? Can someone tell me exactly what is used? I was going to learn the stuff beforehand so I don't have any problems and can finish stress free in a semester with limited amount of time.

Are there videos in courses in these majors or the MBA, or are you just reading text all of the time?

For the computer science major I'm worried about the discrete math 2 and algorithms 2 courses, and for the IT major I'm worried about the SQL course, and for the MBA I'm worried about accounting and economics and finance courses. Are there any resources someone can share that will make these easy? Are the MBA courses on study.com or somewhere else similar? Thanks.
