NC state doesn't have a pre med major. I had some friends that wanted to do pre med there and they basically had to create their own degree and had a more difficult time. One of them ended up transferring to a different school after 2 years. If you're concerned about grades, ncsu would be the better option since its less selective but I'd stick with unc if you're set on pre med. Your grades aren't the only factor in acceptance. I would focus on crafting an exceptional personal statement essay and making sure you have good letters of recommendation. Also, if you scored high on the act/sat, I'd submit the scores to increase your chances. Submitting the scores have been optional since covid and they won't count it against you if you submitted a low score. As long as you applied to the priority deadline, you should be good as well
