"If you're just going to scratch your balls in my class and correct me, you're going to reproove".
Note that "reprobar" means "to fail" in spanish so that might be a direct translation.
Why shouldn't I scratch my balls if I'm forced to take a CAE course by my school and I've taken the test last year? Also, why shouldn't I correct you if you make a mistake every five seconds? You're teaching a generation here yo.
