Question

is this grammiticaly correct

Looking at the 0 on his test, the boy said "Well, I'm a genius"

Answer 1

Almost — it’s understandable, but punctuation and style need small fixes.

Problems and fixes:
- Put a comma after said and the final period inside the quotation marks (American style).
- Spell out the numeral: "zero" or use "a zero" for natural prose.
- The introductory phrase "Looking at the zero on his test" correctly modifies "the boy" (not a dangling modifier), so that part is fine.

Corrected versions:
- American style: Looking at the zero on his test, the boy said, "Well, I'm a genius."
- Slightly more natural: After seeing the zero on his test, the boy said, "Well, I'm a genius."

(British-style punctuation would use single quotes: Looking at the zero on his test, the boy said, 'Well, I'm a genius'.)
