On the last day of school, Miss Martin presented many awards, but she was most excited to present one very special award: the Most-Improved Student Award. She gave it to Peter and said, “Your spelling was perfect in your last paper. I’m very proud of you.”

(from an English textbook for junior high school students in China, co-published by DC Canada Education Publishing and Heibei Education Press)

I wonder if ‘in your last paper’ could be changed to ‘on your last paper’.

Thanks a lot in advance.
