Dear Kusha, there have been complaints that few candidates are unable to download their score card. This must have been due to techncal glitches. I would suggest you to wait for few more hours before you try to download again. It will be rectified hopefully. 

But I just heard from my cousin that she tried this: Hit F12 after logging in. Click on the 'Sources' tab. To the left, you will see an option called Index with some code. Click anywhere on the code, hit Ctrl+F and search for the intax '{'score":'   no backquotes. You will see a higlighted text. You may get to see your score when you scroll to the right. I cannot authenticate this its just a hearsay. Good luck!
