So next year I have to choose options. I am really confused on what to take, but mostly want to do engineering. So, I get very good grades for Physics and Chemistry (2nd Last year exam) but that is because I revise thoroughly, I mean buy extra textbooks and revise from school material and extra. What I mean is, I am not that clever if I would not revise. And I know many people who are just naturally talented, I mean they understand everything easily and know alot of basics. My question is if I do IB HL physics and chemistry there is lots of applied knowlege stuff, so would I do fine?
Also, to do HL Physics do you have to be naturally talented at it, or if you study alot can you acheive the highest results?

Oh, btw IB HL is just a very rigorous education course (harder than A-levels)
