At my school we're graded using percents out of 100.
I'll list the grades I usually get.
Math: 98-99
Science: 95-98
Language Arts: 98-100
Social Studies: 96-98
Music: 90-95
Spanish: 99
Technology: 94-95
Art: 90-95
Home and Careers: 90-95
Reading: Not sure since this is the first year we have it as a graded class.
PE: Anywhere from 85-98
Choir: A (the only letter grade)
I'm not sure what I'll have in reading and I only have it 1 quarter out of the year. Right now I have Technology, next quarter I'll have art, after that I'll have Home and Careers, and then Reading the last quarter.
However, we recently took our reading level tests on the computer and I read at a college level, apparently.
