Math

I'm not very good at math, but we are having a math placement test for 8th grade tomorrow. I'm in 7th grade, and my math teacher said that if we do good on it then we will be in advanced math in 8th grade. If we don't do good on it, then we will be in regular math in 8th grade. I want to do well on it, so I need help and I have been trying to find a 24 hr homework hotline for 30 minutes, before I clicked on StudyDaddy.
