Rephrase: So where does kendo fit into your school? We all will generally agree with the general list of life priorities, family work kendo. There really is no deviating from this. However, there are times when a nice break from studying to do so kendo will do wonders for reducing stress level and get you to return to your studies with added energy. You need to find the balance. Also, if it helps, show up for half a practice. Even that is better than nothing. As long as the sensei or club members understand you are leaving for valid reasons, maybe this will help you to fit both into your schedule and people will understand that you aren't skipping out, just trying to cover all your bases.
