Although there are no solid statistics about this, it's safe to say that the success rate is embarrassingly low (at least when it comes to learning a language for recreational purposes). While it's true that most high schools in the U.S. require that their students study a foreign language for 1-2 years, this only teaches them rudimentary grammar and some basic vocabulary (more or less what one would learn from reading a foreign-language phrase book). If they really want to learn to learn a second language, they have no choice but to study the language on their own. This task takes a hefty amount of time (ranging anywhere from a year to a decade, depending on the language and the desired level of proficiency) and requires plenty of dedication. Unfortunately, attempting to learn a new language is often akin to making a New Year's resolution - it may seem exciting at first, but most people give up within a month after realizing how much work it entails. There are a scant few that do master a second language in high school, but these are the exception rather than the rule.

The hardest language to learn fluently? Here's the answer. The hardest language to learn is most likely to be Chinese. It takes 7 years of fluency. By the time you are born and you start speaking Chinese, and after 7 years you are too good for it. If you're a Chinese reading this, I suggest you learn other languages. (Not just Chinese.)
