Jason is a good student.
Also, he’s in a separate box because he’s hiding in a closet. Which we know because it said “closet” on the door.
This is from Batman Annual 12, which was published in 1988, and was Jason’s only solo Robin story. Retroactive continuity and modern portrayals of Jason — and that includes fan commentary — serve to paint him as incompetent, a failure, not smart, etc., but this shows that Jason was smart enough to have the highest average in his class: 94.8%.
Which is pretty freaking smart, thank you very much.
