What does this question even mean? 'Bad subjects' is not an objective statement, it depends on which course you are applying to, at which university, and which subjects you actually excel in. Sure, if you wanted to become a doctor for example, your A-Levels are completely useless, but it doesn't seem like that's what you're interested in anyway. Exam boards wouldn't offer subjects if they thought they were completely pointless and that nobody cared about them - they could save thousands in costs by stopping the subject spec. The fact that the subject exists means that someone somewhere cares about it. The question is what YOU actually want to do as a career, at degree-level, etc. Figure that out first and then you can decide whether your subjects are 'Bad'.
