我在南马路小学6年级3班怎么写?

I'm in Class 3 Grade 6, Nanmalu School.

I'am in Class Three Grade Six in South Of the Road School.

I'm in Class 3 Grade 6, Nanmalu Primary School.
I'm in Class Three Grade Six, Nanmalu Primary School.

南马路小学,作为特殊地名，南马路应该直接用拼音翻译出来，而不能翻译成south road。

I'm in Class 3 Grade 6, Nanma Road Primary School.
