The AS year for me was Quantum phenomena and Electricity for Unit 1, and then Unit 2 was Mechanics and Waves. Electricity was really boring for me, but the other 3 were really interesting.
I'd say you may well enjoy it, there are many in my class who don't particularly care for Physics compared to Maths, but they still excel in it due to the strong mathematical links, and I think the problem solving aspect is enjoyable in the same way the Maths part is.
I actually find it better than Maths, since Maths you are working in theory and the problems you solve don't necessarily apply to a situation, but the Maths covered in Physics are all real world problems and solutions, and it's more satisfying to solve a problem and realise the effects that there are in the real world.
The most interesting parts for me were the modules such as particles, including working out the motion and energy levels of them, the photoelectric effect; where matter emits electrons as they absorb energy, depending on the energy they absorb they release electrons with a specific wavelength and colour. And also the De Broglie wavelength/wave-particle duality, where every particle has wave like properties and every wave has particle like properties, for instance at a high enough velocity a cricket ball could diffract through the wicket without moving the wicket!
