ucl arts and sciences

I am interested in applying to UCL for psychology , and I have predicted grades of 776 for the IB. Although UCL is my dream school, I am aware of how competitive the program is, with only 1 of 9 applicants being accepted. Additionally, I only received a grade of 6 for Bio HL.

Considering this, I am also contemplating applying for the Arts and Sciences degree program. I have a great interest in social sciences, and I believe that this program would benefit me greatly due to its flexibility, allowing me to primarily select psychology modules. However, if my ultimate goal is to become a psychologist, would this degree program not be the best fit? I would appreciate any advice from individuals who have studied this course!
