As before mum of Architecture student just about to finish BA and start journey of Part 1 architecture
A levels English Lit .....helps him write projects, schemes, be literate!
Geography.....obviously helps understand built environment topography etc etc
Product Design....helps with building models, spacial awareness, developing a project from initial idea to eventual design
( you obviously need the ability to draw as well..but he didn't do Art gcse or A level) He also didn't have Physics as a sepeate subject at gcse think he did the science combined gcse (bilogy physics chemistry in one gcse...he got an A)
As Bubbles says Architects design the building to the clients requirements etc and then it's up to the far more scientifically and mathematical structural engineers to try to make it stand up!!
Universities are looking for creativity and sometimes off the wall ideas in the portfolio rather than any interest in science per say.
They are looking for someone who can envisage the space and how people will use the space......Architecture is about people and place and how the building interacts with the current environment whiilst showing innovation.
Its a very hard course as your ideas are constantly being challenged and critiqued and in the end you are more than likely only going to be designing your new local Asda
Creativity is the key Art or Product design are the key.....biology if she really likes but it won't be at all relevant in her application I'm afraid
But from attending open days they really don't care what GCSE or A levels you have but portfolio is important and any work experience and we also went to London and did some of their day courses at RIBA
