I faked sick all the time in high school. The second semester of my senior year (this past year) I faked sick almost every week because my schedule was so stressful
Usually I would just tell my mom I had a migraine since I do actually get them occasionally. Some days I would just straight up tell her I didn't feel like going to school, lol, and she would write me a note anyway.
I ended up with like ~25 missed days my senior year and ~18 each year before. Not all of them were faking sick, obviously. Half of them were from concerts/vacations/genuinely sick. My school went after people when they had more than 10 missed days in a year since it's state law but I was one of their top students so they never bothered me
