Should I choose business or further mathematics for alevel?

I have already chosen economics, mathematics and chemistry, but I am wondering if I should choose further mathematics or chemistry as I aim for 4A* actually. I don’t know if I would choose which one if depends on my interest. Also, I am planning to study international business and global management or medince in university, so which should I choose?

Don't do a 4th A level. You don't need it. It doesn't give you any advantage and it leaves you a little pressed for time and studying and you will potentially underperform in your exams as a result of the increased work load. You have high ambitions, clearly, but triple A* is a very impressive achievement that you don't want to jeopardise by wanting quadruple A*

Those are two very different careers you're considering. Medicine is incredibly hard and ultra competitive and... have you researched the work life of doctors? It's long hours and hard stuff. You need to be absolutely insane and crazy about Medicine to do it. You need to think about it and research a lot about it. You still have time to make up your mind, after all you're only in year 11, but when it comes to the moment of applying to university... if you want to do Medicine, it's because your heart is 150% set on it and there's no other subject you'd rather do. If that's not the case, then you should choose business.

Actually, I should clarify that. Cuz the universities in hk requires a minimum for 3A (the subject I would like). While the medicine is 4A, so that’s why I would like to choose 4 subjects. I rlly need some suggestions abt which subject will be better if I do have to choose the 4th
