stor 151/155 difficulty

hey! im a prospective unc student who got accepted a few days ago but one of my biggest concerns of the difficulty of these two classes. theyre pre-reqs to apply for the school of nursing, and i am not the strongest math person and it takes me a bit to get concepts, but im a super strong science person (hence nursing). i was wondering if anyone had any comments/advice about these classes? or could kind of gauge the difficulty for me 🩵 thank yall
