There are definitely two days off every week and that's Saturday and Sunday. Those two days I spent at least 120 minutes studying. After that, I helped my parents with simple chores such as babysitting, cooking, and cleaning the house. I spent those jobs on Saturday and Sunday will be rested and entertained after 1 week of continuous schooling. I really enjoyed that precious day. Oh, thank you saturday and master.
