The 2012 season sees a minor change in the way this competition runs! When you make a race prediction that entry will be valid for all remaining races in the season. If a driver is changed for another driver (i.e. Vettel is replaced by Warwick) then your driver choice WON'T be changed!
Everything else works in the usual way; each race is locked for predictions at midnight at the beginning of the friday when Free Practice 1 runs (Thursday for Monaco). If you place a driver correctly you'll get their points, 1 place away gets you half the points while two places away gets you a third of their points. Each of those point awards is rounded up to the nearest 1.
The forum member with the greatest number of points at each race will be awarded The Bernie (Knew the Result of an F1 Race Before It Ran), the winner of the season will get a perfect digital 2D replica of the WDC trophy. Trust me, you can't BUY those things!
