Mathyone, when my daughter was in 8th grade algebra 1 she struggled to get her B+. Everyone else was acing the course. A few months into the class the teacher asked all those who have taken algebra before (over the summer, online, tutor) to raise their hand. Only 2 kids did not raise their hand. And that was the first time I learned about the “underworld” of pre-taking classes so the kid can get an A.)
It happens extensively in our school district. I cannot believe how many compliant, obedient kids will pre-take classes to help get an A or do summer school to get 1 or 2 years ahead in math, science or even History (which frees schedule up for more AP science classes!!) Not only do I think this is unnecessary but I do not think I could get my kids to do this.
