Nope. Premed prerequisite classes don't require any kind of special intelligence (in my opinion). Some people may have to study a lot more than others to get the same grades, but I think the vast majority of college students could do well in the prerequisites if they put in real effort.
Like another poster said, it comes down to how willing you are to sacrifice free time to grind flash cards/anki/re-writing notes and working through practice problems. Sometimes you have to do some self-reflection and figure out why you are struggling and change study methods mid-class, which is time consuming. Sometimes you have to go to office hours/tutoring/SI sessions/watch dozens of Youtube videos to figure out why you don't understand something. In my opinion, the hardest part of the prerequisites is sacrificing things you'd rather be doing to get good grades.
Some of the lower-level classes made very little sense to me (looking at you, cell bio) and I worked through them by purely memorizing every line on the powerpoints while not understanding anything. The material didn't click till higher level classes when we were applying that foundational knowledge and things started clicking because I could see the whole picture now and not just random facts about cells. It was extremely time consuming, but I knew I wanted the A so I put in the time to grind it out.
It's also important for you to realize that A's aren't the only finish line. B's are okay too. You just have to do your best and be okay knowing that you put in the most effort you could while also being a human and taking care of everything else in your life. I have more than a few F's, C's, and W's on my transcript and I got accepted to a MD school. I am confident I will fall short of perfection at least a million more times, both academically and otherwise, on the route to becoming a physician and that's okay. I'll learn the lessons from it and move forward.
