I also took German and ended up minoring in it. Its a wonderful language: straightforward, logical and structured. That said, its not very easy, at least in the beginning. Its very different from the romance languages like Spanish, French and Italian that we all see in high school. So, the intro course is usually not an easy course--I got a C+ in my first German course, which put a crimp on my GPA. But it gets much easier, after you start learning how the language works. Anyway, it might make you stand out from other applicants to MS if you stay with it--most people are aware that German is a tough language so it makes you look like you prefer a challenge. Anyway, best of luck!
