Now, before we go anywhere, I'm sorry if this is in the wrong place. If so, can someone direct me as to where it should be. I'm currently in middle school/high school education level. (Early 9th, but have yet to learn anything new, so....). I do love physics and mathematics, and they're a passion of mine. Our school required biology in freshman year, so no physics. However... my sister took physics last year. I opened her book, and frankly, the problems were all ridiculously easy. I'm not ego talking here, but after everything I studied, they were simple. It makes me wonder now, should I skip directly to AP Physics B? ALthough it was never taught, I know trignometry (I taught myself for vectors), and differentiation (this is fairly low level, but I can differentiate polynomials, products, division, etc....). I've had a lot of negative feedback upon asking my relatives, who have said "Oh, it'll be far too difficult!" However, with my current knowledge, I'm fairly sure I can do it. Obviously though, I want a second opinion before going anywhere. I'm pretty sure everyone here is probably way better than me when it comes to physics, so they probably have a better idea than me of what physics B entails (as I've seen our school's physics A/Honors physics book already). Do you guys feel that I could do it?
