Ditto. I passed first year by the skin of my teeth. Keep in mind that the correlation between first-year performance and research productivity is low (in the population).
Btw, I struggled a lot my first year in classes. I ended up doing well only once I got into field courses and then my own research. So if you are also struggling in first year and not encouraged by your first year profs but excited about research, hang in there.
