8th grade academic question?

Okay by columbia I ume you mean Columbia University. You are still in middle school and they only look at your high school grades. However, if you are not completely satisfied with your grade try to see what happened in the first semester. The first semester can always be challenging and you are in Math Honors of course it is going to be hard. For example, I am in the eighth grade myself. I take math honors as well so I know what you are going through. Your grades do not define who you are. I know it sounds cliche but it is true. Hanging with the smart kids can do that. Mark your progress. Is something bothering you? Try sitting somewhere else as where. That can cause a problem.
