Esteban Gutierrez concedes time is off the essence as he gears up for his Formula One debut next month in Australia.
With pre-season testing limited to just 12 days, Gutierrez is spending just six in his new Sauber C32 while his team-mate Nico Hulkenberg is behind the wheel for the remaining six.
Asked during a live chat with Autosport.com whether he had enough time to be fully prepared, the 21-year-old said: "I'm doing my best, but yes, it's a very short time, only six days in total
"It's not easy of course because as a rookie you need a lot of laps and seat time to adapt, but this is what we have and what I'm trying to get the most out of. Basically it's my only focus at the moment.
"We will see at Melbourne. It will be my first experience of a Formula 1 race."
With his debut comes an increase in pressure with the Mexican racer admitting that while rookies need time to adjust, teams want results.
"I think that the main change between GP2 and Formula 1 is from a psychological point of view.
"There is more media pressure, you are exposed basically to the whole world from a media point of view. And of course it's the top level so the result is the only thing that counts.
"At some point you consider the rookies coming in need some time to prepare and to adapt to the situation, but at the end of the day everyone expects the best results from the drivers."
The best measure in Formula One, though, is to up against a team-mate with Gutierrez saying his goal is to be at Hulkenberg's "level.
"I am going to take it step by step, because he has three years of experience in Formula 1 and I cannot expect straightaway to beat him. But he is a great reference for me, I know that. I am going to work on being at his level this year."
