I hated my high school. I wasn’t challenged at all and the teachers had jobs solely because they were relatives of the Menahel.
My parents arranged for me to take college courses during the day and attend shiur at night. As long as they were paying full tuition the school was just fine with it. By the time I finished high school I had 33 college credits.
About 3 years after I left, a new Board of Directors took over and cleaned house. My younger siblings had a better experience after that.
