I can't get to the International A license test for some reason. I have 49 stars and finished the GT All Star Championship with 4 gold and 1 bronze. I completed all the Mission races in Bronze, I got bronze in the cone challange in Coffee Break,  and I got a gold in the onemake corvette challange. What else do I need to do to get to the International A License?
