Those 4 are all good subjects to choose at AS, but I would recommend dropping the subject you find to be weaker or the one you lose the most interest in after you finish AS. As universities only require 3 subjects and there really is no advantage in having 4.
I too took maths, chemistry, and art (but I had physics too, which I dropped after AS as it was too hard.)
I would only recommend choosing further maths if you REALLY like maths as it will be very hard. All my friends dropped it. But you are not them so you might find it easier who knows.
Art will be very time consuming and I totally regret choosing it, I should have taken computer science instead of as that is what I am going for haha
Ok now for the courses:
- For a medicine type course, a majority of the universities need chemistry as well as maths, physics or biology. So I suggest you take maths and chemistry.
- For computer science the top uni's require maths and the rest will have an option of maths or computer science. So you don't really need computer science, but it will help.
- For a scientist/data research, it is the same subjects for medicine/pharmaceutical courses.
- For accounting, there is no requirement, but the ones that will help are maths, accounting, economics, and business studies.
- For any art related subjects, you only need art and maybe maths if you were to go into architecture.
I really don't think you need further maths, but take it if you really want to. I would suggest maybe biology to help with medicine or something else.
Before A levels I didn't know what I wanted to do exactly too. I had a few ideas for doing animation or some type of engineering. So I took the subjects that would open the most paths for me (maths, chem, physics, and art)
But soon after I told my parents about my animation career idea, and they soon told me to let go of that idea as they said I probably won't get a job. But this is not the case, there are many opportunities. (They are Asian and think I should go with the traditional fields lol)
Then I jumped between different engineering areas such as aerospace, mechanical, civil and software. Then the time to apply for uni came out of nowhere so I chose software engineering. But changed it to computer science as it has a higher scope and I can do software engineering as a job if I want to (assuming I get the degree of course haha)
I didn't choose any of the other engineerings as physics will play a big part and physics was SOOO hard for me.
But ye now I applied for computer science and no idea what I am in for. So I suggest you find out a lot of info in the next year for each career path so you know what you want to do.
But it's still okay if you don't know what you want to do with your life as there are many 25+year-olds who are still lost. xD
You essentially want to choose the subjects you are most interested in and the ones you enjoy the most. As when it comes to revision it will be much easier. (GCSE's are nothing compared to A levels. Trust me.)
Wow this is was long haha
enjoy
and good luck
