A level subjects

I am planning on doing something in Ai or computer related for undergrad. I have already decided on Maths, Physics and Computer Science for my a levels. As a 4th subject which subject should I keep? And are psychology or business good options and if yes which would be better? Also is biology necessary for AI? Thank you

Have you looked at the entry requirements for AI or computer related degrees?

Most are only asking for A Level Maths + 2 other A Levels of your choice. Physics and computer science are not required. In fact, if you want, you can swap out physics and computer science for psychology, business, or biology.

Other than A Level Maths, it's really up to you. If you want to look into robotics or electrical engineering, physics will come in handy.

Bioinformatics (quantitative degrees) isn't available at undergrad level, and these postgrad degrees tend to ask for a quantitative undegrad with programming e.g. computer science, engineering, maths, physics.
I have yet to see business information system courses that extensively look into AI, but even then business studies is not a required subject.

Thank you for the reply. I do plan on keeping cs, math and physics no matter what. The issue is with deciding on an extra subject and am not able to decide whether business or psychology would be a better option. As for bio I don’t like it AT ALL and absolutely do not want to take but I heard from someone that it’s needed for AI in some unis but I haven’t found any which has such requirements so is it a necessity?

Also which subject is it more likely to get an A* in business or psychology? And which one has more memorization?

I haven't come across an undergrad degree in AI that requires biology. I know there are applications of AI in neurology e.g. neurolink by Elon Musk.
The only degree that sort of comes close is Keele's degree in Data science and neuroscience: https://www.keele.ac.uk/study/undergraduate/undergraduatecourses/datascienceandneuroscience/#entry-reqs. Even then, biology isn't strictly required.

Interestingly, Keele's degree in Data Scien and Applied Business Informatics doesn't have any required subjects: https://www.keele.ac.uk/study/undergraduate/undergraduatecourses/datasciencewithappliedbusinessinformatics/#entry-reqs

AI applications in biology is usually something reserved for postgrad degrees e.g.

Which subject you can get an A* in depends on which you personally can do better in. It's more on an individual basis than something you can generalise. They're subjects different enought hat you would require different studying strategies to do well in them.
Psychology requires you to know the psychological studies in detail as well as the research methods. Business studies requires you to apply the material fluently. It's difficult to say.
