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

[MNomadic]

There are YouTubers and posts on the internet saying people have graduated from start to finish in 6 months or one term. And if you type WGU 6 months into Google a lot of pages related to it show up.

Is 6 months not realistic for most people do you think? Like people working full time or maybe not and just devoting all their time to WGU?

With WGU, once you enroll, you can't transfer any credits. 

Transferring in the max credits is better to give yourself the best odds of graduating.

Is the content of courses easier, or the overall program easier, compared to regular colleges?

For example I've noticed in the computer science major there's no operating systems course or a compilers course. Some schools have a required operating systems courses, and some schools have a required compilers course, but WGU has neither as required.

I was going to do the max number of transfer credits from Sophia, Study.com, certifications like those from CompTIA, etc. and would only need to do a few courses at WGU, which seems doable in one semester that's 6 months long.

Every school is going to have different required courses and yes, WGU's BSCS does have a required operating systems course. "Easier" is going to be completely subjective. Some CS degrees require up to calc 3 and linear algebra which WGU does not.
