I just finished my junior year in high school. In college, I hope to major in physics and was interested in the honors versions of freshman introductory physics. These all have the prerequisite of a calculus-based mechanics course and use Kleppner as their mechanics textbook. I have so far only taken a high school honors mechanics course at the level of AP Physics 1 (algebra-based). It seems that I can still place into college honors physics if I learn calculus-based mechanics. I'm not sure what the best way to go about this is. Should I try to learn from University Physics or similar or should I go straight to Kleppner Mechanics, knowing that it'd be the same book I'd use in college? I'm leaning toward the second route because a higher level book might be more interesting and I would have to buy/rent Kleppner anyways later. Would Kleppner be overwhelmingly difficult as a self-study for someone who hasn't taken calculus-based mechanics? I did very well in my algebra-based mechanics class and got 100% on the final. Additionally, I took AP Calculus BC this year and found that extremely easy as well.
