I meant cumulative unweighted, so combined for those two years…maybe that’s on the transcript?
I would not worry much about the B in 8th grade. B’s (and lower) in 9th-11th will matter much more.
Make sure she takes core courses in each of the five core subject areas (eng, math, sci, Soc studies, foreign lang) all 4 years. She should also take bio, chem, and physics.
What math classes will she be taking in 11th and 12th?
