I found physics alot better because it seems more useful and is easier to learn. It may be harder than chemisty but I liked it alot more...It also depends on how far your class or classes go. Im now taking Modern Physics in High School and there is a killer ammount of Calculus in Quantum mechanics and even in some of the simpler physics equation from regular physics which now have Integrals and Derivatives replacing some of the parts from regular physics.
