You don't have to have any relevant qualifications or experience to be considered. Indeed, most cadets don't have an engineering or scientific background. It's more important that they think you have the qualities and potential to get through the course rather than what bits of paper you possess.. .Provided you're serious enough about being a pilot and that you've made some efford in gaining some background knowledge about the company and aviation in general then you should be able to reach the third stage of the selection process which is flight grading. From then on it all depends on whether you can fly or not. Mind you some enthusiastic graders who might not have scored very highly compared with others got admitted.
