Firstly, I have to provide some background information: I am a junior in high school. I recently switched schools. In my previous school, my classes were all centered around chemistry and biology, but I am not interested in those, so at my new school, I want to pursue math and physics, but I am not good at them, even though I am really passionate about them. I do not know how to start; I am in desperate need of useful websites, channels, and books. (Additional info I am in ib program's foundation year, and i want to choose Math AA and Physics for HLS in DP1)
