Last year I took all 4 core subjects: Math, Science, Reading, and Social Studies. I have differen't kinds of tests though. Each one is probably 2-4 hours long, so I take one a day, but each state is different, for me I take the OGT's (Ohio Graduates Test, I think it's pronounced/spelled/whatever)
I think this year, now that I'm in High School/Freshman/Frosh/9th out of 12th grade, I'm going to be taking exams.
OH JOY!!!!!!)
