It depends on what you want to do in university.
If you want to study maths, pick any of these.
If you want to study computer science, pick anything, albeit physics may be more relevant.
If you want to study chemistry, pick chemistry.
If you want to study physics or engineering, pick physics.
If you want to study economics, pick economics.
If you want to study chemical engineering or chemical physics, pick both physics and chemistry.
If you have no idea what you want to do in university, pick which one seems like you would do better in it.
