Plz help...what to do?

Hello Friends, I am the examinee of final 2nd group starting from 11th may. My 1st group was cleared in last attempt. My problem is that I m completely untouch with my study since last one month because of my illness. Although I m not feeling well, but my mind is in great confusion as whether I should appear in exam or not. I am also thinking to study only IDT from today to 16th may for trying to get an exemption since its a scoring paper and almost 14 days is in my hand. I have completed first revision of all subject by the end of march. Plz advise me what to do m really very confused. Thanks in advance.
