How’s the ASU Online workload?

I’m currently studying abroad taking both classes with my program and ASU online classes. I have 4 in person, relatively easy, 3 credit classes and I’m looking to take at least 2 asynchronous classes for ASU online. I’m trying to see what my limit would be workload-wise for session B coming up soon. Can anyone who’s taken classes tell me how hard they are and how much time they may take up? I have plenty of free time so I’m not pressed on that front.
