What A Level should I take to become a Psychiatrist?

Hi, I have just finished my GCSE's and I have to pick my A level's. But I have a problem. Id love to be a psychiatrist or psychologist but I struggle with chemistry. I have personally looked around and most Universities expect at least 2 sciences mainly chemistry and or biology. I have considered to take psychology, biology,english for my A levels but I need to pick one more subject. Can you please tell me if there are any possibilities of not taking a chemistry A level and still getting onto the course or if there are alternative routes that I could take . thanx
