Grades are important in high school, especially of you plan on going to college.
I graduated HS with a 3.3 GPA and was got into University of M. Tuition is about $3,000 a semester, but even with a 3.3 GPA, I get around $6,000 worth of scholarships and grants!! meaning i get paid to go to college :mudkip:
So, yes grades do matter especially when you get a nice $3,000 refund check every semester

just for going to class and doing some work.
