Don’t worry too much about how you’ll do in college. First, focus on what you’re learning right now. Think about getting a review book; I recommend 5 Steps to a 5 over the others for this class. Maybe watch some Khan Academy videos, or read the textbook. Also, keep in mind that AP Physics 1 is supposed to be challenging. When they reworked the exam, they really made sure to test students on their conceptual understanding of the material, not just plugging in numbers.
I think you’ll be fine. You said you get calculus, so I’m assuming you have a good grasp on math, and physics is, at it’s core, just an application of math.
