“College algebra” is not referring to linear algebra, but instead to the introductory level of algebra that used to be taught in middle school and was expected, at worst, to be mastered by the 9th grade.
I would have been kicked out by 9th grade.
Precisely
You still have to work the problems
My son took College Algebra as a dual enrolled student in 10th grade. He said it was easier than the pre algebra he took in 8th grade.
