Economy-Growth rate estimates?

Varun

Recently, following organizations/institutions predicted India's GDP growth rate for financial year 2012-2013
ADB = 8-9%
RBI in Q3 policy review = 5.6%
CSO (Advance Estimate) = 5%

I've following doubts
1. What are other institutions which predicts GDP growth?
2. Which of these predictions are considered to be official via GOI?
3. What does Advanced Estimates (as done by CSO recently) mean? Is it determined by extrapolation?
4. Are all these forecasts important characteristic of an indicative economic policy and not imperative one?

Please help me out.
