Sounds reminiscent of the situation I faced when I was doing my exams. I too was in the same dilema regarding comp no & not being in India.
Unfortunately there is no alternative. If your application does not include your comp no, then its a no go. There is no way around this. The only suggestion is to get over to India to sort all this out - it worked for me, I hope it can work for you.
Good Luck
