30 percent in math, 40 percent in math

Yesterday, we met a friendly young 13 year old. She was with a friend. We know the friend. I asked the friend how she was doing in school.  Then I asked the young 13 year old.  She said in a matter of fact manner that she was doing fine except for math.  Her math is in the 30 or 40 percentile.  Her comment was, " I do not understand math anyway".  She has an  A in math resource class.  I asked if she was on an IEP and the answer is no. An IEP is an individual educational plan to help struggling students with learning challenges or disabilities.  How do the teachers even try to teach these students?
