I started college the same time my youngest entered K-5. I was having trouble juggling my homework with housework and family obligations. I found that if I took care of my family obligations and did not touch my school work until early morning things went smoother.
I started getting up an hour earlier. I found I was able to concentrate and do my homework without distractions (I even got up early on Saturday and Sunday). I also had some sleep and was able to start fresh. I finished my degree program with honors.
