Confused???

I dont know which AS & A level to pick and which to drop, global perspectives and research or economics? (and i have to choose at least one them). My other subjects are math, physics, computer science. I might study in psychology, or law, or IT(software engineer, cybersecurity, AI, etc). And also, which one is more valued and respected in universities, (and more likely in the future). Which one to choose and which to drop? Please help me out.

When do you have to make this decision by?
Generally I would say economics is more "respected" but obviously that really depends on what you are applying for. For all of the the subjects you listed that you might want to study, neither are particularly relevant (although global perspectives might be helpful for law and maybe psychology).
Do you know which one you are more likely to enjoy? This should be an important factor in your decision.

i have to make my decision before this week ends. I dont really know which one i will enjoy more, boths seems pretty interesting and fun. I heard that some universities sees global perspectives as SUPPLEMENTARY SUBJECT instead of core subject, so i am kinda uncertain. Im also interested in finance/business(but currently not planning to take it as a career) so i thought econ with help. Since i have little time left, it is even harder to choose.
