A-levels for Cambridge Architecture

I am about to choose my A-levels, considering my preferred future is to go to Cambridge to study Architecture. I also wanted to balance some more social sciences as part of my A-levels to add variety, so my current decision is Maths, Product Design and Psychology.

I am also considering a fourth, given we have the option at my school, but I am concerned about the work-life balance given I would probably use it for another heavy science-based subject.

Would these 3 options be enough to get me into Cambridge (provided I do well), even if I chose not to take a fourth?

Thanks. Is Art interchangeable with Product Design, given the sketching and design-based work? I know that a few colleges prefer Fine Art, but I wanted to know if this was the general consensus. What about the extent of impact of Psychology instead of Physics?

Would these A-levels put me at a disadvantage compared to other applicants? Also, what are some other factors other than the subjects at A-level that could influence my application strength? I’m currently aware of the grades I get in A-levels, portfolio, entrance exams and interview.
