17.5 credits too much?

Hi friends, I am a freshman at IU and I am trying to figure out my second semester schedule. Would this workload be too much? I am taking 15.5 credits right now, and I think I have a pretty good handle on things.

bus-k204
bus-a207
bus-L293
bus-t175
econ-e201
hisp-s280

I personally wouldn’t want to take 17.5 credits especially with 3 honors classes, but if you’re willing to put in the extra time then it’s not impossible. Also doesn’t this schedule add up to 16.5 credits?
