Sauber's F1 rookie has targeted registering right from the start in the Australian Grand Prix in less than two weeks' time.
The Brazilian, who finished third in GP2 last year, will be making his grand prix racing debut after joining Sauber for the 2015 season.
Nasr has had an encouraging pre-season with the Swiss squad, which struggled last year and failed to score a point for the first time since it entered the sport.
The rookie feels Sauber has managed to turn its fortunes around since the end of last year.
"I'm feeling confident," said Nasr after wrapping up his pre-season at Barcelona.
I think we're going to be in the mix, and have opportunities to score our first points in Melbourne
"I have to say realistically we made some good improvements over the winter and compared to last year's car it looks a lot more promising.
"And I think were are going to be in the mix. So I'm hoping with the opportunities we have to score our first points in Melbourne."
Nasr was the second busiest driver of the pre-season – only behind Mercedes' Nico Rosberg – with nearly 650 laps covered.
The Brazilian says that has given him the confidence to feel ready to go racing.
"The mileage I had in the car, I couldn't have asked for more. I feel comfortable, I feel ready. I can't wait to get to Melbourne and get everything done."
