The Frenchman, who returned to F1 this year after an abortive start to his career in 2009, showed good pace in Australia and Malaysia but failed to see the end of even the opening lap.
In China, therefore, the pressure was on the reigning GP2 champion to finally record a result, and he duly finished sixth -- his first ever points in F1.
"Relieved? No," the Swiss-born driver told RMC Sport.
"No, the work has just paid off. There is no need to put your head on upside down after two races (in 2012). We all know there are ups and downs in motor racing."
Nonetheless, 26-year-old Grosjean admitted it "felt good to fight with Red Bull, Ferrari, McLaren (in China) -- it's great!"
