don't know what to do at uni with my a levelsWatch
I have considered history, international relations with politics but i don't do politics as an a level and maybe business
Are you particularly interested in one subject over the others? there are many degrees where they won't have subject specific requirements, you could also do a joint degree or something like liberal arts and sciences since you're interests seem to be quite varied.
Aside from those slightly obvious options, you could potentially apply to a very wide range of courses. Pretty much any degree except most STEM courses for direct entry, most language-based courses (usually require the/a language to A-level, although there are some exceptions e.g. classics or some ab initio languages), economics (including PPE, usually requires A-level Maths), usually English literature (normally requires that subject to A-level), and most creative/design courses (at least directly; usually require a creative A-level or a foundation art diploma) will accept any combination of A-levels, although they may have some preferences.
Your combination might be particularly amenable to courses like archaeology, which has both scientific and historical elements, or psychology which has both scientific and essay-based/qualitative aspects. Something in between those like human sciences/biological anthropology might also draw from both sides of your options.
Quite a few social sciences, such as politics and geography (NB some geography degrees require A-level Geography) involve some quantitative aspects which your background in chemistry might give you some aptitude for, and your other subjects should generally prepare you well enough for those. Courses like philosophy (i.e. in general, rather than of science specifically) and law draw from both interpretive and analytical approaches that you'll have developed in your non-science and science courses respectively.
You may also find something like the history and philosophy of science or science in society type courses interesting, if you want to learn more about the underpinnings of scientific thought and method without focusing on the actual scientific theories themselves. There may also be scope to focus on the social, political, historical, and/or philosophical aspects relating to science and technology in some of the other courses noted above.
Even though you've only taken once science subject, most STEM courses are available as a "..with foundation year" variant where you will spend a preliminary year 0 studying any scientific content you might have missed before joining the first year of the course. So you could apply to almost any STEM subject as a result still, if you find you do enjoy STEM areas a lot and you just didn't take the right combination to pursue that.
