I not only did Physics, but the first year of a physics and Astro degree (hence my user name).
But it wasn't much fun, it became almost neat maths. I hadn't done further Maths or even got a brilliant ordinary A Level. I was sunk.
I didn't want to be an engineer like my Dad, but I thought I wanted to do something women didn't do. I never minded being one of only two girls.
In the end. I became a biologist (fortunately I'd twisted the HTs arm to do 4 A levels)
I'd done Biology for fun, the degree course was fun too! Varied and interesting.
That the problem with Physics, sexist though it is, that sort of dry abstract detail doesn't hold most girls concentration.
Yes, I like biochemistry, genetics and the technical end of biology rather than ecology. But even the most intricate workings of a cell are linked to medicine and the real world.
