I know that in colleges that recalculate grades, they do not add in those courses taken in tech, vocational, etc. schools. While it may be wonderful hands on experience, if he is aiming for a selective school, he will have less time to take more rigorous courses. If he is thinking of going to a college and take higher level math and science classes, it may be more beneficial to take as many math and sciences in high school to prepare him for college level classes. The more selective colleges will also want to see 3-4 yrs of a language, will the schedule allow for that? I agree with @thumper1 , don’t make your decision based upon admission to med school.
