Hi there,
I am going to offer you some practical advice here. Take it for what it is worth. Here goes: The highest score that I ever achieved on an IQ test is 100 (dead average). I finished undergraduate with double major in Biology and Chemistry and a double minor in Math and Physics. I finished graduate school (Biochemistry and Molecular Biology) and medical school (now a PGY-4 General Surgery resident). I well on MCAT and all USMLE Step and the LSAT. The point of all of this is that if I can do this with my dead average IQ, you can more than get through any of the sciences and medical school.
My key is that no one (including myself) ever told me that I couldn't learn anything that was of interest to me. As a physician, I am a life-long learner. I simply love learning new things and I can always find an application for them. I love knowing why the sky is blue and why the grass is green. I love the practical, critical thinking of the New England Puritan writers like John Winthrop. I love Immanuel Kant's Critique of Pure Reason. I love that I read the New Testament in the original Greek and that I understand the Latin of the Pope as he speaks from Rome. All of this stuff has made me a Dam--ed well-educated person.
As you go through life, you want and need the challenges. Any new thing of learning is good for your mind and you can find usefulness for your newly acquired knowledge. If nothing else, all of my education has taught me to listen to my patients with an open mind and really hear what they have to say. It is a good trait for any physician and it has made me pretty good a diagnosis. It is through the filter of my very diverse education that I hear and learn everything.
Look at your science courses to come with the eye of a person who wants to learn. You have been able to learn and master the Paramedic stuff, what is going to stop you from doing the same thing with General Biology, General Chemistry, Organic Chemistry and General Physics? Each new course is an opportunity to learn and master new knowledge. Odd thing, medical school is the same way!
Do NOT think yourself or talk yourself out of anything. You have brain cells so put them to work and keep an open mind. You want to become a physician so give yourself the tools to do so. If I can do this, anyone can do this. It just takes meeting every challenge with an open mind and a strong belief in yourself. Believe me, I am nothing special. The greatest thing that I have at this point is that I genuinely LOVE what I do and I was not afraid to stretch myself and do what it took to prepare for this profession. I also have an ability to turn a deaf ear to anyone who tells me that I cannot do or learn something.
Hang in there and enjoy the journey. It is totally loads of fun along the way. You cannot know success without failure so learn from your "bombs" and put them in your arsenal of experience but move forward. Just think about how many times you fell when you were first learning to walk but now you move without thinking about it. Learning new stuff works the same way. 👍
