The metaphorical eight ball

My students this semester have low-level English skills, and it’s my job to teach them the same material that everyone else is teaching to higher level students. It’s challenging: I have little experience with truly low-level students, and the material I’m teaching is better suited to the higher-level students, but I’m responsible for getting them to meet the same standards as the higher-level students.

I am behind a metaphorical eight ball.
