Please, I really need to know this before 14 march, 2024

So I need to choose my subjects for IGCSE, I m choosing, all science, maths, Eng, Arabic, Islamic, social studies and I need to choose one more subject before 14 march, but I m confused which one, I m really interested in GCSE psychology but I will drop it after my IGCSE is done because I will take medical, so the problem is that should I choose an easier subjects likes arts or food and nutrition so I can focus of my main subjects more or should I just take GCSE psychology, I m really interested in it but don’t want to mess up my grades in my main subjects, help me what do I do, tell me will it be harder if I take psychology also with those subjects?
