There's no need to get all butt hurt over this. We here in PH can't answer your question because 1. every high school/school district has different graduation standards and 2. You're engrish make no cents.
When I was HS, students had to have 2 credits of Math in order to graduate. If your school is anything like mine, then you wouldn't need to have a math class your junior year if you already took and passed math in 9th and 10th grade. However if you want to go on to college after HS (good luck), it's recommended to take math all 4 yrs of HS.
I swear, someone already explained this in the 1st page of this thread. And we have to give her some credit...at least she found the correct subforum to post this question.
