People saying 'natural talent' are delusional. A Levels do not require an inch of talent, they require you to pay attention in class, revise, and make an effort to understand what you are taught so you can apply it to exam questions, which are generally very simple and predictable. Exams which test 'natural talent' are olympiads, and maybe STEP, but even they can be mastered with hard work and experience, but that is all talent really is. Obviously under achievers don't like to admit this.
