After a slightly odd three week break, Formula One gets back to the day job with Free Practice in China. The first two rounds of the 2012 season have been completed, and have thrown up a few surprises, and as the European leg of the year creeps closer, we should start to get a better feel for who is fast and who isn't. With 90 minutes of practice to complete, drivers will be trying out the tyres and any new parts developed over the break to try and get a better understanding of their still-new cars.
