Dear Keerthana, the only document you will need to take to the exam along with you is the Admit card. For downloading the admit card, please login with your credentials at the page http://joinindianarmy.nic.in/Alpha/login.html. Click on the "Officer's Entry Apply" or "Login ". Use the User Id and Password and enter the Captcha code. The admit card will be displayed. Check for any discrepancies in the admit card. The details that need to be checked are Name, Photograph, Exam Centre Details, Exam Schedule and Exam day Instructions. If they are all good, download the admit card as an Identity document to the exam hall.
