Which A levels are you doing and what are your main interests?
Try linking the two things. For example, I was really interested in minerals, which really link into inorganic chemistry, due to transition metal ions affecting the colours and ionic compounds that comprise the minerals having characteristic structures that affect the shapes of the crystals formed (of course the list goes on, but alas, I digress).
When I learned of this, I ended up studying chemistry to the point where it actually became really enjoyable, as it helped me develop a better understanding of minerals and I also became well aware of important applications of chemistry elsewhere. I’d say that now chemistry is my main interest of all things, so clearly this can work.
