You really want things as high as possible. It’s possible to match without great stats but you will have a harder time. I had a 3.2 and was just below 50% on my class rank. (Side note: at the place I did my residency a student with a 3.2 was like bottom 15% of her class so grade inflation is real folks, which is why class rank matters). I ranked a lot of places for internship and matched very low on that long list (to a practice I had visited which I 10000% think helped). But I matched to an internship, got a residency, and now I’m boarded. A lot of places won’t consider you if you don’t have outstanding stats but visit places, talk to people, apply smartly, and it can be done.
My main advice is to continue to work hard and give yourself an upward trend. That will be the best way you can “make up” for a sub-par period. Luckily, if you’re only one semester in, there’s still more time to change things than if you were a third year. I had Cs first year. Second year I had mostly Bs with some As, and by third year I had more As (but still plenty of Bs). But it showed progress that my only Cs were back in first year. But I also think stressing about grades only makes it more stressful, and if you aren’t even sure you want to specialize, I would just focus on doing the best you can do, make connections, and not focus too hard on the exact numbers.
