it's good to be curious
Bascially, quantum physics is a rather new branch of physics. Classical physics is what you are learning right now. Quantum physics addresses things that classical physics cannot explain. One example would be electrons being able to function like a wave, i.e. undergoing diffraction. Classical physics states that only waves can have diffraction, yet this phenomena was observed in an electron beam
U will touch a little on the borderline of quantum physics at A levels. You will learn light as a particle instead of a wave, and electron beam as a wave instead of a particle => wave-particle duality. However, that's not all. There are still theories on gravities as particles (gravitons), and many other other things... The list is very long
