15 credits term - too much or doable?

[boblax]

I'm currently planning my BA CS + BS BA second degree, and I'm planning on doing a 15 credits term at TESU that would include:
SOS-1100: Cornerstone
LIB-4970: Liberal arts capstone
CIS-1070: Computer concepts and applications ePack
CIS-351: Software engineering
PHI-1300: Intro to critical reasoning

I'm already a software engineer. I tried the CIS-1070 TECEP preview and passed, so I'm assuming the ePack shouldn't be an issue and won't take me more than a couple hours.
Not sure what CIS-351 is about (I read that there is actually no programming), but again I think maybe 10-15 hours total should be enough.
Which leaves me with the other three, the cornerstone, the capstone which I read is quite time consuming, as well as intro to critical reasoning.

I can dedicate about 30h per week total (4h per day 7/7 give or take). Would it be doable to complete these 5 courses in a single term, and possibly score As in all of them?

Cornerstone isn't hard.
Capstones are always a lot of writing, so be careful there.
The other 3, I'm not sure on the workload of those specific classes.
Depending on how comfortable you are with the subjects, I think I would try it, but I tend to bite off big bites for short periods instead of many small bites. Just have a plan on which you will re-do/drop if you have to.
