Changing requirements after you apply is open for legal challenge.
When in college, they kept changing the requirements to graduate. It was like trying to hit a moving target. I challenged it and won.
We have two homeschooled sons—a senior in high school and a senior in college. I’ll grant you that neither are math geniuses, but both are successful. Our oldest is about to graduate and begin a career as a health care professional and the other is exploring his options after high school. Both are mature, engage well with adults, work hard and are emotionally stable young men. I get that homeschool may not be for everyone, but in my experience, the graduates I’ve seen are highly prepared for life.
