Trying for "Most Rigorous" but what about scheduling issues?

he’s hoping to go MBA route. There’s a 1 trimester MVC course at his HS he will try to take senior year. And H Physics, which is math-y. He will have exhausted all options at his HS at that point. And isn’t that what colleges are supposed to look at? What is available at his HS? I am so opposed to high school students feeling pressured to enroll in actual college courses. Isn’t that what college is for? No way can a college freshman be behind just because they haven’t already had linear algebra.
