Well, there are lots of degrees available that aren't specifically linked to any A-level subject. Most degrees outside of STEM areas have no or few required A-levels. And most STEM degrees are available with a foundation year even for those without the "correct" A-levels.
What is it you're actually interested in learning about? What do you take the time to read more about when given the opportunity, beyond just preparing for exams and suchlike?
There are plenty of courses that may be of interest, but there are far too many to possibly list. Sanskrit, linguistics, marine biology with a foundation year...there are innumerable less common degree subjects, and even more conventional ones!
