I didn't appear in all the papers, but still I want to tell you that the sole consideration while selecting subjects should be your interest and aptitude. There is no such thing as high-scoring and low-scoring subjects, as trends change from year to year, some year a certain history is scoring, next year it isn't, same is true for urdu. Just choose the subjects you find interesting so that you find them easy and are able to do your best, and here you go!
