very sorry to hear dat but dont worry brother there would be some good will in this n u will get above 40.... never loose courage i myself struck with a blow when after a preparation of a year almost fortunately or unfortunately i got typhoid fever on the starting date of exams so could only manage to attempt compulsory subjects when my illness did not allow me to proceed but i did not let my spirit deflated.... It is like Darwins theory of natural selection to be selected in CSS so be happy
