hi,

see age is not  a bar if you are really interested to gain knowledge, however I would not recommend you to take science if you have no interest in pcb or weak in pcb. you may skip biology, you may take computer science or statistics or geography in place of biology but to continue in science stream physics and chemistry is necessary. now since you are interested for media jobs related with journalism or mass communication you may take arts, or you may take commerce , where you will have subjects of  Accountancy, Business Studies, Economics, and English as main subjects. Apart from these subjects, a few optional subjects are Mathematics , Informatics Practices, Entrepreneurship, and Physical Education.
