I've been composing before I even started school, so maybe it's just me, but I find it hard to believe someone can just, while studying at a conservatory or such, become a good composer if they've just looked at the list of what classes to take, and said "Oh, composition! That sounds cool." and actually become a good composer.
Because composition, I think, is something natural, and not something you do just because you're taking a composition class in school.
What do you think?
Can anything good come out of only school-based composition?
