If you study psychology in the future, the requirements for English are naturally not generally high, or just like studying law, they are all majors with the highest requirements for English. If you want to learn psychology, you can't write and read without getting a score of 7 in IELTS, among which writing is very demanding.
I don't know your English. At least before I went abroad, IELTS was 6, so it was difficult to learn geography. Finally, I left economics behind, because I was good at it, so I studied well, but I still felt that English was not good. If it's psychology, I haven't studied it, I'm not sure, but I don't recommend you to study it. First, English. Second, universities don't like it.
The most ridiculous thing about going abroad to go to A-level is what major you want to study after college and go to high school. If you really have college goals, you can look at the admission requirements. Take accounting as an example. LSE is a clear statement that no matter which major in our school, we don't like A-level accounting. So, firstly, it is difficult for you to get an A, and secondly, I don't like college. So what is the purpose of your study?
At the end of high school, we should learn some basic subjects, mathematics and further mathematics, and then choose two subjects from physics, chemistry and biology. Don't ask anything, you ask which science student's bad psychology belongs to the medical category, science in science. Personal recommendation, choose biology, and then choose physical chemistry. If you learn well, you can learn all of them.
Your preliminary plan for science, geography, economy and psychology is useless at all. It is not easy to get an A and an A*.
Specific things, you go to the university of official website to see, what subjects people want, what subjects they don't want, they will be very clear and don't be subjective.
Further math is omnipotent, but if you are not good at math, then it is ok not to learn, as long as other things are well coordinated, which cannot be said to be a disadvantage.
