Rating

Impossible. Too many aspects affecting OTB result in a complex way. Long time ago I found similar test and I was rated an IM. It was based on positional understanding or choosing of candidate moves based on GM games. It didn't measure my weakness in tactics.
Why not just pick an OTB player around your predicted rating (here at chessdotcom) and play some games. If you score 50% then you might have equal rating OTB.

I know. Was just trying to find a solution

Not really. Around 5 tournaments. The rest is on chessdotcom. But I know about the physical and mental challenge during OTB tournaments. I have problem with long distance transport as well.
Here, in one swiss (rapid) tournament we usually play 9 games. 12 at most.
Hello every body. I am looking for a good site to tell me my exact rating through comprehensive tests.Anyone can help?Do you know any good websites for this?
