Both my children have been homeschooled; my daughter is a Senior, president of the local chapter of the National Honor Society, gorgeous and intellectually intimidating to most men, and accepted to the USCG Academy starting in June. My son is a Sophomore, also an officer in NHS, speech & debate, TeenPact, competitive sailor, blackbelt in TKD, worship leader at our church ... he's essentially done with High School, but still studying as he wants to get into a University that only takes 20 new students a year. They didn't get there from memorizing facts prioritized by a social engineering agenda, no matter how scientific they might appear.
Our desired endstate for both of them was critical thinking skills ... data, facts, are only useful if you have the skills to process that data in a rational and reasonable manner. And to synthesize those facts to answer the question, what does that mean to me? goes into the other classical sciences of theology and philosophy, which they've also studied. My biggest disappointment in our public school system is that they focus on which pieces of data they want the kids to memorize, and then test them for memorization skills. But the ability to think, question and reason are left on the shelf to give more time for socialization, sex ed, and secular religion.
Whether its Jefferson or Calvin, much of that is sincerely a waste of time since all they're going to know at the end of the day is a name, some dates, and barely a fraction of a percent of who they were. Id rather they study the history of ideas.
