Or German at 16. I teach high school German in Norway, and the kids don't hear/read enough German for immersion to work. We have 4 hours per week of classes, so memorization of vocabulary and grammar is fundamental. (but some combination with immersion is obviously very preferable) But: There is no silver bullet. Take The Korean too with a grain of salt (but there is a lot of truth there)
