Hi there, may I ask if you have any plans for after your A-levels? This helps a lot in deciding what A levels to choose. If not, I'd always, ALWAYS, suggest taking a subject that will bring you as much joy as possible. The next 2 years of study will be intense at times and choosing subjects you will truly enjoy studying in your free time and revising will make that time feel as worthwhile as possible. Have you considered English language, or classical civilisation, if your place of study offers it? These often go well with English literature. Alternatively, biology and sociology seem to be paired regularly with psychology. But again at the end of the day, choosing what you will like studying will help the most by far in your decision. I hope this helps and you have a great 2 years of A levels!
