I know, but it's some very unimportant subjects that can easily missed. Plus I'm neither physically nor mentally able to go to school atm. So it's not really skipping, just taking some time to heal. Totally not trying to find excuses...
If you want skip, I can help you. Go for the bathroom, stay on that for 30 minutes without do nothing/doing something, flush. If your parents ask, you can say: "Dad, I've bellyache... It's hurting too much. I'll skip today, okay?". If they give you medicine, well, don't take it. Only take if they ordert to do in them front. So, be happy in your free day
