Felipe Massa believes his career has taken a step forward thanks to his year testing at Ferrari.
The young Brazilian was sacked by Sauber after proving quick but erratic last season and Ferrari immediately signed him up to complement regular tester Luca Badoer.
His departure from Sauber looked like Massa's final act in Formula One but he believes he is now a more complete driver.
He said: "Here, I have learnt and am learning a lot. For me, Ferrari is proving to be an incredible school.
"Working with Michael Schumacher, Rubens Barrichello and Luca is like going to university.
"The experience I am acquiring this year is very important, especially as I go to all the races and attend all the meetings. The more time I spend with the team the better it is for me."
