Will my LL.M GPA effect my future employment in the US?

I am planning to take 1L classes during my LL.M program in order to be better prepared for the bar. However, since 1st year of law school is so crucial for the law school GPA and, accordingly, a future employment, JD students will kill themselves trying to succeed in classes. This makes my chances, as a foreigner, to receive high grades in the classes pretty small. I've heard several opposite opinions regarding correlation between the GPA & classes of interest.
Can't make a decision.
