Training is what you get in college! The stuff in high school is what eeeeveryone has to learn. :) Biology isn't useless to a biologist, or a doctor, or a pharmacist. And grammar isn't useless to an author or a journalist or a scientific writer. It's all just giving you the basic idea of what everyone else does, so that even if you end up never using it again, you can still appreciate what everyone else does.
You too, have a great 2015!!
