Hi Santosh,
Have you associated your adsense account at IRC and ISC? Only if you are creating new accounts you have to wait till you are a Gold member, I think. I am not sure, Rajmi would be knowing better.
I took sometime more because I was just concentrating in IRC when IRC was just new. Adsense was not paying much then. My spurt started only this year and I have finished my first 100$ by the end of April, just within 4 months.
You can, if you add quality resources, reviews, give links by answering queries at Yahoo, ammas, ibibo etc. Improve your page content, you will get more adsense revenue from here than at ISC, because the ads are costly here.
Just go around and do what all you can. Do not look at your adsense, it will start moving up soon all by itself, as your viewers increase.
